a CLASSID attribute. If you do not specify a default group policy, and there is no CLASSID, the
security appliance can not establish the session.
• Authorization Settings—Lets you set values for usernames that the security appliance recognizes for
IMAP4S authorization. This applies to IMAP4S users that authenticate with digital certificates and
require LDAP or RADIUS authorization.

johndoe. He must authenticate as johndoe@cisco.com. If you choose EA and O, John Does must
authenticate as johndoe@cisco.com and Cisco. Systems, Inc.
