This plugin bridges external HTTP authentication systems, such as Shibboleth or Kerberos, with a standard user management system. It is designed for administrators who need to authenticate users via an external service while maintaining a local user database for exceptions or specific interfaces. The tool provides flexibility for mixed authentication environments.

• Mixed Authentication Support: Allows the system to authenticate users from an external source while also permitting standard username and password logins for users not present in the external system.
• Flexible Interface Handling: Provides options to use standard authentication for specific administrative interfaces, such as XML-RPC or Atom, simplifying setup where HTTP authentication is difficult to configure.
• Customizable User Attribute Sync: The code structure allows for modifications to automatically update local user profiles with attributes, like name and email, passed from the external authentication server.
• Robust Session Management: Includes updates to improve the login and logout process, addressing edge cases to ensure reliable user authentication and session cookie handling.
• Compatibility Updates: Maintains functionality across different versions of the underlying platform, with fixes for warnings and CSS to ensure stable operation.
