- Add ValidateSession gRPC method for proxy-side user validation
- Move group access validation from REST callback to gRPC layer
- Capture user info in access logs via CapturedData mutable pointer
- Create validate_session_test.go for gRPC validation tests
- Simplify auth_callback_integration_test.go to create accounts
programmatically instead of using SQL file
- SQL test data file now only used by validate_session_test.go
Implement user group validation during OAuth callback to ensure users
belong to allowed distribution groups before granting access to reverse
proxies. This provides account isolation and fine-grained access control.
Key changes:
- Add ValidateUserGroupAccess to ProxyServiceServer for group membership checks
- Redirect denied users to error page with access_denied parameter
- Handle OAuth error responses in proxy middleware
- Add comprehensive integration tests for auth callback flow
