Complete rebuild of the plugin
* Fix bug affecting Azure OIDC authentication ( and most likely others ) * Fixes issue #51 * Ensure that appended roles are unique. Update the documentation. * Improvements targetting possible memory usage spikes. * Additional fixes and cleanup * Refactoring code to fix the issues identified by the users. * Modernize run * Fieldalignment * Multiple changes to improve performance and reduce complexity. - Optimise the errors and recovery. - Deduplicate code in metadata cache. - Remove unused performance monitoring code. - Simplify session management and settings handling. * Fix claims issue. * Add ability to overwrite the default scopes in the settings file * Well.. that escalated quickly. Completely forgot that Traefik uses outdated Yaegi and requires compatibility with 1.20 ( pre-generic Go code ). * Bugfix #51: Ensures that user provided scopes overrides work. * fixup! Bugfix #51: Ensures that user provided scopes overrides work. * fixup! fixup! Bugfix #51: Ensures that user provided scopes overrides work. * Abstract the provider logic into a separate package. * Additional micro fixes and cleanups. * Simplify all the things. * fixup!

Cleanup 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. * CSRF and Cookie Domain fixes * fixup! CSRF and Cookie Domain fixes * Metadata cache leak fix + profiling * fixup! Metadata cache leak fix + profiling * Memory leaks hunting, part 1337. * Further pursue of perfection. * fixup!
