We just upgraded to 2.2 and implemented LDAP and SSO. We've created test account users so our Librarians can demonstrate using Moodle. In 1.9, we could log out and use the login block to log in as a different user. In Moodle 2.2, SSO takes over and always uses who is logged into the computer.
Are we missing a setting that suspends SSO if the login block is used?
