Plugins - Login Authentication
Category: Logging in

This plugin tells SquirrelMail how to understand when users have been externally authenticated, in which case the SquirrelMail login page is unnecessary. Common uses of this plugin are for environments that employ HTTP authentication or have implemented single sign-on systems. Remember that SquirrelMail still needs to authenticate against your IMAP server, so SquirrelMail still needs to know what credentials to use and how to get them. Assuming you've coordinated your IMAP authentication with your external web authentication, this plugin helps with those tasks.

[ login_auth-3.0-1.4.0.tar.gz tarball (14311 d/l) Help ]
Requires: SquirrelMail 1.4.0+, Compatibility 2.0.7+ (unless using SM 1.4.10+ or 1.5.2+), PHP Zlib support (only if you are using the compression feature with the "authenticated_saml" module)

  • Added the ability to use this plugin for other external login systems (aside from just HTTP authentication), such as some single sign-on systems.
  • Thanks to Emmanuel Dreyfus for help with the "authenticated_saml" module and Victoriano Giralt for help with the "trusted_saml" module
  • Added compatibility with the Login Manager plugin
  • Added configuration file that allows administrators to fine-tune the behavior of this plugin, particularly if using a custom single sign-on system. Those using HTTP authentication do not need to create a configuration file of their own - the default behavior will suffice in these cases.
