* implement certificate posture check
* log signal address
* add keychain and cert store support
* read the console user's keychain through a user session helper
A root daemon cannot reach a login keychain: securityd is per session and a
key ACL needs a session to prompt in, so dropping uid is not enough. The
daemon now answers certificate challenges from the System keychain itself,
where MDM installs device identities, and launches "netbird posture
cert-proof" into the console user's desktop session with launchctl asuser
for the login keychain. Only the signature and the chain cross back, never
the private key.
The console user comes from SCDynamicStoreCopyConsoleUser, bound with purego
like the keychain calls. The login window reports no user, root, or
"loginwindow", and all three are treated as no keychain to read, so a Mac at
the lock screen sends device proofs alone.
Adds info logging across the path: the keychain search list, per class query
status and item counts, the chain built per candidate, and the verification
error for every rejected candidate. A run that sends nothing now says why.
README.md documents the trust model, the console user limitation and how to
read the logs.
* read the signed-in user's certificate store on Windows
A service reads LocalMachine\MY, where AD and Intune enrol device
certificates. CurrentUser\MY lives in the signed-in user's registry hive
with keys protected against their profile, and a service that opens it does
not fail: "current user" resolves to HKU\S-1-5-18, so it silently reads the
service account's own empty store. The service therefore reads the machine
store itself and launches "netbird posture cert-proof" with the session
token for the rest, mirroring the macOS console user helper.
Windows lets a privileged service assume a user identity, so the token goes
straight into the child process and no external tooling is involved.
CREATE_NO_WINDOW keeps a console window from flashing on the desktop every
sync. In-process impersonation would also work but is per OS thread while
goroutines migrate, so the child process avoids that class of bug.
Session selection prefers the physical console and falls back to any active
session, so remote desktop and VDI hosts are covered. WTSQueryUserToken
needs SE_TCB_NAME, so a user-run client skips the helper and reads the
machine store alone.
SystemStore takes a store location, gaining NewUserStore alongside
NewSystemStore and the per candidate logging macOS already had. The request
building and proof merging move to helper_spawn.go, shared by both
platforms, and helperStore picks what the helper reads per platform.

* [client] Read TSS2 key files on go-tpm, checked against the library it replaces
The TSS2 parser was the only reason this repository depended on a crypto suite
whose own build tooling it inherits. The replacement sits on go-tpm, which was
already a direct dependency and is in fact what that suite calls underneath, so
this removes a wrapper rather than porting onto a different library: the load,
the derived storage root key and the signing commands are the same calls.
Swapping a parser on the one path a customer actually runs is not something to
assert, so the two are held side by side for this commit. One test feeds the
replacement bytes the old library wrote and requires the same key type, empty
auth flag, parent handle, blobs and decoded public key; the other feeds both the
fixtures the tests are built on, so those are the shape the format calls for and
not merely the shape the new parser reads. The scaffolding goes away with the
dependency in the commit that follows.
The encoder behind the fixtures is written out separately from the parser under
test, so an encoder bug and a decoder bug cannot cancel each other out.
* [client] Drop go.step.sm/crypto and the repo-wide upgrades it imposed
The TSS2 parser was the only thing in the repository that used this module, and
it brought 302 modules into the graph to do it — 35 of them linters, along with
Google Cloud KMS and IAM, the AWS SDK and a terminal styling library. Those are
the module's own development dependencies, which minimal version selection turns
into floors in ours, and they are the whole reason gRPC, protobuf, the AWS SDK,
OpenTelemetry, logrus and five x/ packages had moved. Management, signal, relay
and proxy inherited every one of them for a feature none of them runs.
Removing the import is not enough, because tidy never downgrades: the raised
floors stay written in go.mod. Each one is pinned back to the version main had,
then tidy is left to raise again whatever something still genuinely needs. It
raised nothing: all 43 are back where they were, and go-tpm was already in the
graph at the same version, so the certificate feature now costs no new module at
all.
The differential tests go with it. They existed to check the swap against the
library while both were present, and there is nothing left to compare against.
* [client] Clear the lint findings only the macOS and Windows runners see
golangci-lint analyses one build at a time, so running it on Linux says nothing
about the two platforms CI also lints. Against those builds the feature's
packages reported eight findings, and the structural one is Config.dir: it is
dead on macOS and Windows because neither reads a directory at all, their
collectors take the configuration and discard it. Moving the method beside its
only callers makes that visible in the layout instead of in a linter, and leaves
the gap itself — no file or token store on those platforms — where it belongs,
as something to decide rather than something to silence.
An absent key file beside a certificate was reported as a nil signer with a nil
error, which the caller then had to recognise by its nilness. It is a sentinel
now, so the meaning is in the error rather than in the absence of one.
The rest follow the standard library: the elliptic coordinates and the private
scalar come from the encoding helpers rather than the deprecated big.Int fields,
and an error string loses its trailing colon.
Lint is clean on linux, darwin and windows; the hardware TPM path was exercised
separately against a real device and passes.

* [management] Renew certificate challenge nonces on quiet accounts
A certificate challenge nonce is accepted for its own window and the one before
it, and it only reaches a peer attached to a network map. An account where
nothing changes sends no map, so after a day the peer re-sends the nonce it
still holds, verification rejects its whole proof set, and the certificates
stored for it are dropped. It fails the certificate check and loses every policy
gated on it until some unrelated change happens to push a map. The outage
repairs itself in seconds, which is what makes it expensive: it is intermittent,
it only hits stable networks, and it is not reproducible on demand.
Push the account's peers an update often enough that the nonce they hold is
never close to expiring. Only accounts whose posture checks actually ask for a
certificate are tracked, so a deployment without the feature does no extra work.
The refresh runs from one goroutine over a map of accounts rather than a timer
per account: the period is hours, so one pass every few minutes costs nothing
next to it, and there is no timer to re-arm when an account that falls due
sooner appears. Each account's first run is offset by a hash of its ID, because
the challenge window is global and an instance restart would otherwise arm every
account in the same moment.
The push carries no administrative change, so it is counted as a refresh rather
than an update and stays out of the figures that track what was edited.
(cherry picked from commit 7ad4a0df37)
* [management] Make the certificate challenge window one knob to turn
Renewal was timed against the window in two different ways: the period derived
from it, the sweep interval did not. Shortening the window to watch a renewal in
an end-to-end run would have left the refresher still looking for due accounts
every quarter of an hour, so nothing would have been renewed in time and the
test would have reported the feature broken.
Derive the sweep from the period, within bounds that keep a very short window
from spinning and a normal one from checking less often than is useful, and
allow the window itself to be set through the environment so a run can take
seconds instead of half a day. A value that cannot be parsed or falls outside
the bounds keeps the default, because a window nobody intended is a security
property nobody chose, and an override is logged at warning level since it sets
how long a device keeps passing the check after its key is gone.
Every instance has to be given the same value: the window is part of the nonce,
so instances that disagree reject each other's.
(cherry picked from commit 0e38fcf409)
* [management] Pin the property that makes per-peer nonce state unnecessary
A nonce carries the window it was minted in, not the instant, and is accepted
for that window and the one before it. So a peer re-stamped at least once per
window can never be left holding one outside the accepted pair, whenever it was
last served and however much life its own nonce had left. That is the whole
reason management tracks nothing per peer, and it was resting on an argument
rather than a test.
The phases are part of the property, not decoration: accounts are deliberately
given a refresh phase of their own, so the guarantee has to hold off the window
boundary too. The negative case shows why that matters — a cadence of exactly
two windows lands inside the grace window when it is aligned to the boundary and
leaves a gap when it is not.
(cherry picked from commit dee68facfd)
* [management] Renew challenges only for the peers that answer one
The refresh pushed an update to every connected peer of the account, while only
the peers a certificate check applies to carry a nonce. On an account where a
handful of peers sit behind the check and the rest do not, everyone was woken
several times a day to be handed a map that changed nothing for them.
Push to the sources of the enabled policies whose posture checks include a
certificate check, which is exactly the set that is sent a challenge.
Resolving the set the other way round than the gRPC layer does is the risk here:
a peer the refresh forgets stops being renewed and falls out of its policies
silently, which is the failure this whole mechanism exists to prevent. So the
selection is held against processPeerPostureChecks, the per-peer rule that
decides who receives a challenge in the first place, by a test that asks both
the same question and requires the same answer.
(cherry picked from commit dc4d0e0274)
* [management] Derive certificate challenge nonces from the stored encryption key
The nonce secret came from the server's WireGuard key, which is generated afresh
in every process and never persisted. A nonce carries no state, so the only
thing that lets one instance verify what another issued is deriving the same
secret — and that premise, written in the comment above the challenger, was not
met: every instance had its own key.
A peer reconnecting after a restart therefore presented a nonce minted under the
previous secret, verification failed with a mismatch, its whole proof set was
rejected and the certificates stored for it were dropped until it signed again.
Reproduced three times on the lab, each one logging "nonce was not issued to
this peer", which only a changed secret produces. On a single instance it costs
seconds of lost policy access per restart; across instances it is not transient
at all, because every reconnect that lands elsewhere is rejected the same way.
Derive from the data store encryption key instead: it is generated once, written
back to the configuration and read by every instance, so it survives restarts
and is shared. Where none is configured the secret falls back to the WireGuard
key with a warning — degraded but still unpredictable, which is the property
that matters most: a peer able to guess it could mint the nonces of future
windows, sign them while its key is present and keep passing after it is gone.
The challenger is now built once and passed to the two places that need it,
rather than re-derived per message.
(cherry picked from commit 278f2f3807)
* [management] Register an account for renewal where its nonce is issued
Renewal was armed when a peer connected or when a posture check was saved, both
of which ask the store whether the account has a certificate check. That misses
the case it most needs to catch: the check is created through one instance while
the peers are connected to another, so the instance serving them never learns it
has anything to renew and their nonce expires. It also charged a query to every
peer connect in every account, including the ones that will never use the
feature, which a fleet reconnecting after a restart pays all at once.
Register where the nonce is actually stamped instead. A nonce is verified from a
shared secret and so travels between instances, but the renewal that keeps it
fresh cannot: only the instance holding a peer's stream can push to it. Issuing
and renewing now line up by construction — an instance renews exactly the
accounts it has issued nonces for — and an instance that never issues one has
nothing to renew, so there is no case left to miss.
The registration is a map insert with no store access, which is what lets it sit
on a path taken by every login and every initial sync.
Reported by Viktor Liu, who also proposed registering at the point of issue.
(cherry picked from commit 2d16dd7d7cf54762f2e64c5630ea092f32ef63ab)
* [management] Register for renewal on pushed updates, not only on connect
Registering where the nonce is stamped only covered the login and the initial
sync, which both happen when a peer opens a stream. That left out the path the
mechanism exists for.
On the cloud the network map controller is wrapped so that an update publishes
to an event bus instead of pushing locally: an instance handling a REST change
broadcasts, and every instance holding a peer of that account pushes to its own.
Those pushes stamp a nonce through the update handler, and nothing there
registered, so an instance learned about an account only when one of its peers
happened to reconnect. For a quiet fleet that is the original bug: the check is
created, the peers are told about it, and nobody renews what they were told.
Registering on the pushed update closes it, and is the difference between
stamping and marking a peer connected — one happens on every push, the other
only when a stream opens. Reported by Viktor Liu; the broadcast that makes it
work was pointed out by Pascal Fischer.
(cherry picked from commit 59efe8d93e53bacdf57cb546f4ab2c19dc4eddab)
* [management] Let the challenge refresh loop stop with the manager that owns it
The loop was started on a context explicitly detached from the caller's, so
nothing could ever stop it. Production is unaffected either way, since
BuildManager is called with context.Background(), but a test that builds a
manager leaked a sweeping goroutine for the rest of the run, and a shutdown
path added later would have had no way to reach it.
Take the manager's context as the request buffer built on the line above
already does. The test pins the contract the loop offers, so a detached
context cannot come back inside Start either.
* [management] Bound one account's challenge refresh so it cannot starve the rest
Resolving which peers answer a challenge reads the store three times, and the
refresher sweeps accounts one after another on a single goroutine. A read that
never returns held the sweep for the life of the process, so every other
account on the instance stopped being renewed and its peers fell out of the
policies gated on the check: one account's bad luck became an outage for all
of them.
Give each refresh the sweep interval it is allowed to occupy, capped at 30s so
a 12-hour window does not grant minutes to a query that should take
milliseconds. A refresh that runs out of time keeps its account tracked, since
a deadline says nothing about whether that account still has a certificate
check.
* [management] Send challenge refreshes down the path the rest of management uses
The refresh dispatched through UpdateAffectedPeers, the one variant that takes
no reason, so it was missing from the update counters and coalesced with
nothing. An administrator editing a policy while the sweep ran made the
account's network map twice over, and UpdateOperationRefresh, added for
exactly this caller, was never referenced.
Buffer it with a posture_check/refresh reason instead. The periodic push is
now visible in the metrics as what it is, distinct from an edit, and the send
detaches from the sweep deadline on its own, so that deadline bounds the store
reads it was meant for.
* [management] Keep the certificate challenge comments to what the history does not say
Four of these ran to three and four times the comment budget, the longest at
992 characters. Most of the excess argued against designs that were never
written or explained a bug that no longer exists in the code, which is what
the commit that fixed it is for.
What is left is the part a reader cannot recover from the code: that the
nonce secret has to be persisted and unpredictable, that stamping and
renewing are decided together because only the serving instance can push, and
that the target rule is the inverse of processPeerPostureChecks.
* Keep the newest posture checks pending whatever made their meta sync fail
* Report no lost certificate when the engine stops during a proof collection
* Share the proof collection single-flight across engine restarts
* Close a PKCS#11 module that loads but cannot be used
* Fix the pending checks comments
* Renew certificate challenges only for the peers streamed to this instance
* Ignore a challenge stamp from an older sync stream of the same peer
* Kill the Windows certificate proof helper with its whole process tree
* Expect the challenge untrack in the session ownership test
* Drop an invalid certificate proof without discarding the valid ones
* Start a system info gathering beside one that has been stuck for ten timeouts

Account settings changes refreshed every peer, even an IPv6 group toggle
that re-addresses a few, and the refresh goroutine got the request context,
so it could be cancelled when the handler returned. Group paths that
reconcile IPv6 addresses only walked the changed group, so peers reaching a
re-addressed peer through its other groups missed the new address.
The IPv6 reconcile now returns the peers whose address changed and callers
pass them as changed peers. An IPv6-only settings change dispatches affected
peers, adding every IPv6 holder on a range change since the interface prefix
comes from the range. IPv4 range and account-wide changes keep the full
refresh with a detached context.
Deleting an account left state behind that DeleteAccount's store
associations don't reach. The Agent Network tables outlived the account,
keeping its gateway domain claimed and its provider API keys stored. The
proxies kept serving its gateway until they next resynced. Cloud-side
state, such as managed proxy deployments, had no way to be cleaned up at
all.
Account deletion now runs registered hooks after the permission check
and before any users or data are removed. A failing hook aborts the
deletion. Agent Network registers one that tells the proxies to drop the
account's gateway mappings. The account's settings, providers, policies,
guardrails and budget rules are deleted in the account's transaction.
Consumption counters, and the access logs of deleted accounts, are left
to the background cleanup; usage records are kept.
With improvements in userspace lazy connection handling, we should be able to enable it for new accounts with less impact on users.
These connections are cheaper and only target traffic that should go through the tunnels, leaving all other tunnels in an idle state.
* [management, client] Add management-controlled client metrics push
Allow enabling/disabling client metrics push from the dashboard via
account settings instead of requiring env vars on every client.
- Add MetricsConfig proto message to NetbirdConfig
- Add MetricsPushEnabled to account Settings (DB-persisted)
- Expose metrics_push_enabled in OpenAPI and dashboard API handler
- Populate MetricsConfig in sync and login responses
- Client dynamically starts/stops push based on management config
- NB_METRICS_PUSH_ENABLED env var overrides management when explicitly set
- Add activity events for metrics push enable/disable
* Remove log line
* [management] Fix peer update test for MetricsConfig in NetbirdConfig
Update TestUpdateAccountPeers assertions: NetbirdConfig is no longer
nil in peer update responses since it now carries MetricsConfig even
when STUN/TURN config is absent.
* Regenerate proto files with protoc v7.34.1
* [management] Read metrics push setting in Postgres account query
getAccountPgx omitted settings_metrics_push_enabled from its hand-written
SELECT and Scan, so the toggle was always read back as false on Postgres
and never reached clients.
* [client] Fix metrics push getting stuck off after engine restart
Engine restarts (backoff retries within the same login session) cancel
e.ctx, which the push goroutine's lifetime was tied to. The goroutine
died silently but ClientMetrics.push stayed non-nil since only an
explicit stop clears it, so the next UpdatePushFromMgm call saw a
"push already running" state and never restarted it.
Give the Engine its own metricsCtx sourced from ConnectClient.ctx,
which outlives engine restarts, so handleMetricsUpdate stops tying the
push to the wrong-scoped context. Additionally make ClientMetrics.push
an atomic.Pointer that the push goroutine clears via CompareAndSwap on
exit, so the tracked state can never drift from the goroutine's actual
lifetime regardless of which context a future caller passes in.
* [management] Regenerate OpenAPI types with oapi-codegen v2.7.1
types.gen.go was regenerated with a stale local v2.6.0 binary,
causing the CI git-diff check against generate.sh's pinned v2.7.1
to fail.
When JWT group sync is enabled with a restrictive JWTAllowGroups list, the local owner of an embedded-IdP (Dex) deployment can get locked out. The allow-groups check runs account-wide but local password users do not receive
external IdP group claims, so they can't satisfy the allowed list.
This skips JWT group evaluation for local Dex users so the restriction and JWT group sync continue to apply to external-IdP users as intended.
* add SSO session extend flow (management)
Adds the management-server half of the SSO session-extension feature:
- New ExtendAuthSession gRPC RPC that refreshes a peer's session expiry
using a fresh JWT, validated through the same pipeline as Login but
without tearing down the tunnel or redoing the NetworkMap sync.
- Per-peer SessionExpiresAt timestamp on every LoginResponse and
SyncResponse so connected clients learn the deadline on the existing
long-lived stream, and admin-side changes (toggling expiration,
changing the expiration window) reach every peer within seconds.
- SessionExpiresAt(...) helper on Peer that derives the absolute UTC
deadline from LastLogin + the account-level PeerLoginExpiration
setting, returning zero when the peer is not SSO-tracked or expiration
is disabled.
The matching client-side consumer of these fields lands separately.
* encode SessionExpiresAt as 3-state on the wire
Previously the `sessionExpiresAt` field on LoginResponse, SyncResponse
and ExtendAuthSessionResponse was 2-state: a valid timestamp meant
"new deadline", and nil meant "clear". That conflated two distinct
meanings — "no info in this snapshot" vs "expiry is explicitly off /
peer is not SSO-tracked" — so a Sync push that legitimately couldn't
compute the deadline (settings lookup failed) would silently clear the
client's anchor and lose the warning window.
Three states now, encoded on the same field number (no .proto schema
churn — only comments and the server-side encoder change):
- nil pointer (field absent) → "no info"; client preserves anchor
- &Timestamp{} (seconds=0, nanos=0) → explicit "disabled / not SSO"
sentinel; client clears
- valid timestamp → new absolute UTC deadline
A new encodeSessionExpiresAt helper centralises the zero/non-zero
encoding and is shared by the Sync, Login and ExtendAuthSession
builders. The Sync builder still emits nil when settings are missing.
Login and ExtendAuthSession always carry an authoritative value.
The matching client-side decoder lands on feature/session-extend.
* add UserExtendedPeerSession activity event
ExtendAuthSession previously reused UserLoggedInPeer for its audit
record, which conflated two distinct user actions: a full interactive
SSO login (tunnel re-established, network map resync) versus an
in-place deadline refresh (tunnel untouched). Auditors reading the log
couldn't tell which one happened, and downstream dashboards/alerts on
"login" volume were polluted by routine extends.
Adds a dedicated UserExtendedPeerSession Activity (code 125,
"user.peer.session.extend") and switches ExtendPeerSession over to it.
The peer-extend audit trail is now distinguishable from interactive
logins.
* make ExtendAuthSession JWT-retry backoff cancellable
Skip the retry log and 200ms wait on the final attempt, and replace the
uncancellable time.Sleep with a select on time.After/ctx.Done so an
upstream cancellation aborts the wait instead of running it to
completion.
* [management] Fence peer status updates with a session token
The connect/disconnect path used a best-effort LastSeen-after-streamStart
comparison to decide whether a status update should land. Under contention
— a re-sync arriving while the previous stream's disconnect was still in
flight, or two management replicas seeing the same peer at once — the
check was a read-then-decide-then-write window: any UPDATE in between
caused the wrong row to be written. The Go-side time.Now() that fed the
comparison also drifted under lock contention, since it was captured
seconds before the write actually committed.
Replace it with an integer-nanosecond fencing token stored alongside the
status. Every gRPC sync stream uses its open time (UnixNano) as its token.
Connects only land when the incoming token is strictly greater than the
stored one; disconnects only land when the incoming token equals the
stored one (i.e. we're the stream that owns the current session). Both
are single optimistic-locked UPDATEs — no read-then-write, no transaction
wrapper.
LastSeen is now written by the database itself (CURRENT_TIMESTAMP). The
caller never supplies it, so the value always reflects the real moment
of the UPDATE rather than the moment the caller queued the work — which
was already off by minutes under heavy lock contention.
Side effects (geo lookup, peer-login-expiration scheduling, network-map
fan-out) are explicitly documented as running after the fence UPDATE
commits, never inside it. Geo also skips the update when realIP equals
the stored ConnectionIP, dropping a redundant SavePeerLocation call on
same-IP reconnects.
Tests cover the three semantic cases (matched disconnect lands, stale
disconnect dropped, stale connect dropped) plus a 16-goroutine race test
that asserts the highest token always wins.
* [management] Add SessionStartedAt to peer status updates
Stored `SessionStartedAt` for fencing token propagation across goroutines and updated database queries/functions to handle the new field. Removed outdated geolocation handling logic and adjusted tests for concurrency safety.
* Rename `peer_status_required_approval` to `peer_status_requires_approval` in SQL store fields
* Add support for legacy IDP cache environment variable
* Centralize cache store creation to reuse a single Redis connection pool
Each cache consumer (IDP cache, token store, PKCE store, secrets manager,
EDR validator) was independently calling NewStore, creating separate Redis
clients with their own connection pools — up to 1400 potential connections
from a single management server process.
Introduce a shared CacheStore() singleton on BaseServer that creates one
store at boot and injects it into all consumers. Consumer constructors now
receive a store.StoreInterface instead of creating their own.
For Redis mode, all consumers share one connection pool (1000 max conns).
For in-memory mode, all consumers share one GoCache instance.
* Update management-integrations module to latest version
* sync go.sum
* Export `GetAddrFromEnv` to allow reuse across packages
* Update management-integrations module version in go.mod and go.sum
* Update management-integrations module version in go.mod and go.sum
Auto-update logic moved out of the UI into a dedicated updatemanager.Manager service that runs in the connection layer. The
UI no longer polls or checks for updates independently.
The update manager supports three modes driven by the management server's auto-update policy:
No policy set by mgm: checks GitHub for the latest version and notifies the user (previous behavior, now centralized)
mgm enforces update: the "About" menu triggers installation directly instead of just downloading the file — user still initiates the action
mgm forces update: installation proceeds automatically without user interaction
updateManager lifecycle is now owned by daemon, giving the daemon server direct control via a new TriggerUpdate RPC
Introduces EngineServices struct to group external service dependencies passed to NewEngine, reducing its argument count from 11 to 4
* **Bug Fixes**
* Fixed domain configuration handling in single account mode to properly retrieve and apply domain settings from account data.
* Improved error handling when account data is unavailable with fallback to configured default domain.
* **Tests**
* Added comprehensive test coverage for single account mode domain configuration scenarios, including edge cases for missing or unavailable account data.
CLI: new expose command to publish a local port with flags for PIN, password, user groups, custom domain, name prefix and protocol (HTTP default).
Management/API: create/renew/stop expose sessions (streamed status), automatic naming/domain, TTL renewals, background expiration, new management RPCs and client methods.
UI/API: account settings now include peer_expose_enabled and peer_expose_groups; new activity codes for peer expose events.
Bug Fixes
Network and DNS updates now defer service and reverse-proxy reloads until after account updates complete, preventing inconsistent proxy state and race conditions.
Chores
Removed automatic peer/broadcast updates immediately following bulk service reloads.
Tests
Added a test ensuring network-range changes complete without deadlock.
Add LocalAuthDisabled option to embedded IdP configuration
This adds the ability to disable local (email/password) authentication when using the embedded Dex identity provider. When disabled, users can only authenticate via external
identity providers (Google, OIDC, etc.).
This simplifies user login when there is only one external IdP configured. The login page will redirect directly to the IdP login page.
Key changes:
Added LocalAuthDisabled field to EmbeddedIdPConfig
Added methods to check and toggle local auth: IsLocalAuthEnabled, HasNonLocalConnectors, DisableLocalAuth, EnableLocalAuth
Validation prevents disabling local auth if no external connectors are configured
Existing local users are preserved when disabled and can login again when re-enabled
Operations are idempotent (disabling already disabled is a no-op)
Embed Dex as a built-in IdP to simplify self-hosting setup.
Adds an embedded OIDC Identity Provider (Dex) with local user management and optional external IdP connectors (Google/GitHub/OIDC/SAML), plus device-auth flow for CLI login. Introduces instance onboarding/setup endpoints (including owner creation), field-level encryption for sensitive user data, a streamlined self-hosting provisioning script, and expanded APIs + test coverage for IdP management.
