The situation is that users expire in AD and Sun LDAP, but SunLDAP will
grant access to users, as long as they exist and the password is correct.

For one of our services, this is a desirable feature.  We want to fail over
to Sun LDAP if the former student is attempting to access their Banner
records to request a transcript, for example, or print a W2 form.

The general consensus is let them authenticate, but if they are not
authorized, the client will prohibit that access.  Personally, I feel we
are swimming in murky waters without a full understanding of how all of our
authentication/authorization systems interact.  Alaskans are very
independent in geneHaving said that, we are using CAS only for
authentication to  Ellucian Banner Products - at this time.
