iRule for Shibboleth integration

The problem is that not every LMS user resides in the LDAP. There are some users which only exist in the local LMS database. So we left two doors to the LMS system - default and Shibboleth. For most of the users its a portal where they start and login. After that the email and LMS are single sign on. But as I mentioned above there is a default login for users who are not in the LDAP. Hope i does make sense :)
