Ldap user root MTA option

Direct LDAP schema MTA options:  (DN)
The  MTA option specifies  the base DN for the user and group portion of the DIT for purposes of MTA LDAP URL lookups. (In particular,   substitutions in  LDAP URL lookups use this value.) This option, if set, overrides the base option    (or in legacy configuration, the configutil parameter  ). If neither the MTA option nor the base option (in legacy configuration, the configutil parameter) has been explicitly set, then the default is.
