The simplesamlphp_auth module makes it possible for Backdrop CMS to support SAML for authentication of users. The module will auto-provision user accounts into Backdrop CMS if you want it to. It can also dynamically assign Backdrop CMS roles based on identity attribute values.

You must have SimpleSAMLphp installed and configured as a working service point (SP) as the module uses your local SimpleSAMLphp SP for the SAML support. For more information on installing and configuring SimpleSAMLphp as an SP visit: http://www.simplesamlphp.org.

IMPORTANT: Your SP must be configured to use something other than phpsession for session storage (in config/config.php set store.type => 'memcache' or 'sql').

To use memcache session handling you must have memcached installed on your server and PHP must have the memcache extension. For more information on installing the memcache extension for PHP visit: http://www.php.net/manual/en/memcache.installation.php

If you are on a shared host or a machine that you cannot install memcache on then consider using the sql handler (store.type => 'sql').

• Install this module using the official Backdrop CMS instructions at https://backdropcms.org/guide/modules.

The configuration of the module is fairly straight forward. You will need to know the names of the attributes that your SP will be making available to the module in order to map them into Backdrop CMS.

Bugs and Feature requests should be reported in the Issue Queue: https://github.com/backdrop-contrib/simplesamlphp_auth/issues.
