Fields
• AAA server groups—Click to go to the AAA Server Groups panel (Configuration > Features >
Properties > AAA Setup > AAA Server Groups), where you can add or edit AAA server groups.
• group policies—Click to go to the Group Policy panel (Configuration > Features > VPN >
General > Group Policy), where you can add or edit group policies.
• Authentication Server Group—Select the authentication server group for POP3S user
authentication. The default is to have no authentication servers configured. If you have set AAA as
the authentication method for POP3S (Configuration > Features AAA > VPN > E-Mail Proxy >
Authentication panel), you must configure an AAA server and select it here, or authentication
always fails.
• Authorization Server Group—Select the authorization server group for POP3S user authorization.
The default is to have no authorization servers configured.
• Accounting Server Group—Select the accounting server group for POP3S user accounting. The
default is to have no accounting servers configured.
• Default Group Policy—Select the group policy to apply to POP3S users when AAA does not return
a CLASSID attribute. The length must be between 4 and 15 alphanumeric characters. 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
POP3S authorization. This applies to POP3S users that authenticate with digital certificates and
require LDAP or RADIUS authorization.
–
User the entire DN as the username—Select to use the Distinguished Name for POP3S
authorization.
–
Specify individual DN fields as the username—Select to specify specific DN fields for user
authorization.
You can choose two DN fields, primary and secondary. For example, if you choose EA, users
authenticate according to their e-mail address. Then a user with the Common Name (CN) John
Doe and an e-mail address of johndoe@cisco.com cannot authenticate as John Doe or as
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.
