Ldap auth password MTA option

Direct LDAP attribute name MTA options:  (LDAP attribute name list)
The  MTA option specifies the name of a group level LDAP attribute, by default , used to store a password needed to post to the group.

In iMS 5.2 the value of this attribute was saved if the  attribute was set to require a password, and the value was then checked against the Approved: field once the header became available. The Approved: field was removed from the header once the check was complete. But this did not allow for routing to the moderator in the event of a password check failure.

In the MS 6.0 release and later, the presence of a  attribute forces a  reprocessing pass. As the message is enqueued to the reprocessing channel, the password is taken from the header and placed in the envelope. Then while reprocessing, the password is taken from the envelope and checked against this attribute. Additionally, only passwords that actually are used are removed from the header field.

Note that the          MTA option acts on the   attribute in the       same way it acts on the other access check attributes.
