Zimbra LDAP Service > Account Authentication

Account Authentication
Supported authentication mechanisms are Internal, External LDAP, and External Active Directory. The authentication method type is set on a per-domain basis. If zimbraAuthMech attribute is not set, the default is to use internal authentication.
The internal authentication method uses the Zimbra schema running on the OpenLDAP server.
The zimbraAuthFallbackToLocal attribute can be enabled so that the system falls back to the local authentication if external authentication fails. The default is FALSE.
