We normally receive that error when the user is authenticated, but not
authorized to use the target application.  In the case of Banner, e.g.,
that application seeks an attribute called the UDC Identifier which is used
to establish role permissions for the various Banner applications.  Once
authenticated, our LDAP returns that attribute.  A similar failure would
occur any attribute the target application is seeking has not been gathered
from the authentication source.
