Record when stale LDAP records are re-used in the AuthorizationSession. The AuthorizationSession is responsible for re-acquiring authorization rights, if it finds that its locally cached copy is stale. Various errors can be emitted during this re-acquisition process, and the AuthorizationSession must handle them.

When an LDAP fault occurs during handle refresh, we should record a unique error message, and explain that we're falling back to stale information. We should write a test which validates that this message is emitted.
