Shibboleth and other auth modules

Prerequisites

• installed functional Shibboleth module in Apache2 (or SW with similar functionality). The installation is beyond the scope of this document.
• installed any other auth module which knows to send username via REMOTE_USER server variable (e.g. mod_auth_openidc or mod_auth_mellon)

How does it work

When enabled in the GUI settings then the GUI search for the REMOTE_USER header (provided by Shibboleth sp) and uses it as auth user.

Configuration

• enable it with GUI->Settings->System configuration : Use Shibboleth/REMOTE_USER for auth
• it still requires some GUI's users for privileges settings
• One user can be setup as default user for Shibboleth. See 'Default Shibboleth/REMOTE_USER account' checkbox in GUI->Users & Audit->Users -> selected user

Usage

• after the Shibboleth/REMOTE_USER auth the GUI's Shibboleth/REMOTE_USER button will appear in GUI login dialog
• after clicking on this button the content of REMOTE_USER header is used as the user in the GUI database for getting user's privileges
• if an user is not found then the user with set checkbox 'Default Shibboleth/REMOTE_USER account' is used (if set)
• login is done

Logout

• the Shibboleth logout URL is constructed from Shib-Handler header + '/Logout' string. If not available then from HTTP_HOST header + '/Shibboleth.sso/Logout' string.
• if you want to use custom Logout URL then set it in GUI->Settings->System configuration : Logout URL for Shibboleth/REMOTE_USER

Disable Login window

• you can disable the login window completely with GUI->Settings->System configuration : Disable login window completely

Usage with custom login script

• it's working
• the REMOTE_USER variable is passed to the custom login script. And your script must return structure as described in WEB_API#Custom_Login
• Note: the GUI's internal users have precedence before custom login users
