Features

Auto Discovery

The login service automatically detects the SAML configuration for the current request based on the sp_entity_id matching your domain.

Deep Link Support (Middleware)

The extension includes middleware for redirecting users to their original destination after login/logout:

• The RelayState parameter should contain the target URL
• Transmitted via POST (login) or GET (logout) from SAML server to the configured ACS URLs

Backend Module

Access SAML metadata via the Admin Tools > SAML Auth backend module to configure your IdP.
