Indicates the access list that is assigned to the
Distributed Director. The access list is a case-
insensitive regular expression that is used to match
against DNS name to address translation requested. If
the DNS name in the query matches the access list,
director processing will be performed; otherwise, the
query will be forwarded in the canonical catching name
server fashion.
The value '0' indicates that no access list is assigned
to the Distributed Director.
