This configuration directive is only available in Movable Type Enterprise.

This configuration directive specifies the authentication type that will be used for user logins. The default, MT, indicates that Movable Type Enterprise's author database is authoritative. The alternate option, LDAP, specifies that an LDAP directory will be used as the authoritative authentication source.

If LDAP is specified, the following configuration directives are also relevant and in some cases required:

• AuthLDAPBindDN
• AuthLDAPPassword
• AuthLDAPSASLMechanism
