Account Authentication
This section describes the following account authentication mechanisms and formatting directives that are supported:

The Internal authentication method assumes the Zimbra schema running on the OpenLDAP directory server.
The External LDAP and External Active Directory authentication methods attempt to bind to the specified LDAP server, using the supplied user name and password. These methods can be used if the email environment uses Microsoft Active Directory directory services for authentication and the Zimbra-LDAP directory services for all other Zimbra-related transactions. This requires that users exist in both OpenLDAP and in the Active Directory servers.
The authentication method type is set on a per-domain basis, using the zimbraAuthMech attribute, with other information also coming from the domain. If this attribute is not set, the default is to use the internal method as the authentication.
