Руководство Пользователя для Cisco Cisco Email Security Appliance C170

If you store user information within LDAP directories in your network infrastructure — for example, in 
Microsoft Active Directory, SunONE Directory Server, or OpenLDAP directories — you can configure 
the appliance to query your LDAP servers to accept, route, and authenticate messages. You can configure 
the appliance to work with one or multiple LDAP servers. 

The following section provides an overview on the types of LDAP queries you can perform; how LDAP 
works with the appliance to authenticate, accept, and route messages; and how to configure your 
appliance to work with LDAP.
