lukaszraczylo 9cbca4c4fb fix(refresh): honor userIdentifierClaim in token refresh path (#132)
patch-release

The refresh path in token_manager.go hardcoded the "email" claim when
extracting the user identifier from a refreshed ID token, ignoring the
configured userIdentifierClaim. Keycloak users without an email claim
(using sub or another identifier) were kicked out on refresh even
though their initial login worked.

The callback path (auth_flow.go:226-239) already honored
userIdentifierClaim with "sub" fallback; PR #100 (commit a316a98)
added that support but missed the refresh path.

Mirror the callback logic in refreshToken so both paths behave the same.

Cleanup: rename Get/SetEmail to Get/SetUserIdentifier on SessionData
to match the actual semantics. The slot already stored the configured
identifier (email, sub, oid, upn, preferred_username), only the API
name was misleading. Storage key "email" → "user_identifier" and
combinedSessionPayload field E (json:"e") → Ui (json:"ui").

Compat note: existing user sessions invalidate on upgrade — every active
user re-authenticates once after deploying this change.

lukaszraczylo bde1db1c3b traefik plugin 0.7.7 (#73)
* Automatic discovery of the scopes.

Issue #61 raised very valid concerns about users configuring scopes that are not supported by the provider.
This change introduces automatic discovery of supported scopes by fetching the provider's discovery document and filtering out unsupported scopes.

Before:
User configures: scopes: ["openid", "profile", "email", "offline_access"]
Self-hosted GitLab: "The requested scope is invalid, unknown, or malformed"
Authentication:  FAILS

After:
User configures: scopes: ["openid", "profile", "email", "offline_access"]
Middleware checks discovery doc → offline_access not supported
Automatically filters to: ["openid", "profile", "email"]
Authentication:  SUCCEEDS

* Resolves issue #74 by enabling user to specify expected audience in the configuration.

* Fix flaky tests.

* Issue #53: Fix CSRF token handling in reverse proxy

1.  HTTPS Detection Fixed (session.go:723)
- Now uses X-Forwarded-Proto header instead of r.URL.Scheme
- Properly detects HTTPS in reverse proxy environments
2.  SameSite Cookie Attribute Fixed
- Removed automatic SameSiteStrictMode for HTTPS (would break OAuth)
- Keeps SameSiteLaxMode to allow OAuth callbacks from external domains
- Only uses Strict for AJAX requests which don't involve OAuth redirects
3.  Cookie Domain Handling Fixed
- Now respects X-Forwarded-Host header for cookie domain
- Ensures cookies are set for the public domain, not internal proxy domain
4.  EnhanceSessionSecurity Properly Integrated
- Function is now actually called during session save
- Applies security enhancements without breaking OAuth flow

Why Issue #53 Failed Before:

1. Cookies were not marked Secure in HTTPS environments (browser wouldn't send them back)
2. If they had been Secure with SameSite=Strict, Azure callbacks would still fail
3. Cookie domain might have been wrong (internal vs public domain)

Why It Works Now:

1. Cookies are properly marked Secure for HTTPS
2. Uses SameSite=Lax to allow OAuth provider callbacks
3. Cookie domain uses public domain from X-Forwarded-Host
4. CSRF token persists through the entire OAuth flow

* Next set of enhancements together with memory usage improvements.

* Memory leak fixes and optimisations.
