ldap_required can destroy an active session more than once

[cjg89]

It looks like ldap_required() is capable of calling ldap_destroy_session() multiple times in a single page load, which will throw a session_destroy(): Trying to destroy uninitialized session warning.

This situation occurs when a user logs in to the UIL lookup, then clicks the "log out" link at the top of the page. I'm not sure yet if there's any other instances where this would occur.
