This can be tested without an actual Shibboleth setup, but please note that after following these steps you won't be able to log back in to the instance without manually disabling Shibboleth. 1. (If not already a Shib instance) Turn on Shibboleth authentication. Make sure the alternative login URL is set in the main Authentication page (this should happen automatically and isn't part of this patch). 2. Purge the site caches. 3. Logout. 4. Attempt to log back in. You should be taken to the alternate Shibboleth authentication page. 5. Verify that the text correctly sets up a link to the Moodle Administrator email account. If you need to recover the system afterwards find the alternateloginurl setting in mdl_config and null it out.
