depends on two source attributes. That always generates a WARN message for every shib login. But I suspect that when this is combined with a user who has no LDAP record that the IDP generates the Uncaught exception (array index out of bounds).<o:p></o:p></span></p>

<p class="MsoNormal">We have some folks (alums) who can still authenticate with our SSO solution, but who do not have records in LDAP anymore. We are running shib IDP v3.2.1 and are using RemoteUser to integrate with our SSO. When a person with no LDAP record
logs in to SSO, the subsequent IDP LDAP lookup fails and we get an "Uncaught exception" from the IDP. Is this expected behavior?<o:p></o:p></p>
