Ldap group dn MTA option

Direct LDAP attribute name MTA options:  (LDAP attribute name)
The  MTA option names an LDAP attribute which may be placed on a group entry in LDAP as one way of  identifying members of the group. The default LDAP attribute name is.

Typically, and in default use, the value in the LDAP attribute named by  is a DN (Distinguished Name), so that the members of the group are being identified via their position (DN) in the DIT. Note that such a DN may specify an entire subtree of the DIT. Specifically, in basic use the value of the LDAP attribute named by  is substituted into the URL template defined by the   MTA option, whose default value is: ldap:///$A?mail?sub?(mail=&#x2a;) where the  (or whatever LDAP attribute named by  ) value is substituted in place of the.

However, the exact use/interpretation of the LDAP attribute named by  is controlled not only by the   MTA option, but optionally may be further modified via the    mapping table, as well as any special mapping table specified for that group  via the group LDAP attribute named by the   MTA option. As of Messaging Server 7.0.5, if a    mapping table exists, then it is used to determine what template (what alternative to  ) to apply to the value of the LDAP attribute named by. The  mapping probe is of the form object-classes&#x7c;attribute-name&#x7c;attribute-value If the mapping sets the  output flag, then the mapping result is used as the template instead of the    MTA option&#x27;s value.

Multiple values of the LDAP attribute named by  are allowed on a group entry, e.g., multiple    values are allowed, but only one attribute name  may be specified as. To use another named LDAP attribute (perhaps in a slightly different way) use.

As of Messaging Server 7.0.5 any mapping specified by the   MTA option will also be applied to the results produced by the   and   attributes.
