+ Active Directory limits the number of members to be
+ retrieved in a single lookup using the MaxValRange
+ policy (which defaults to 1500 members). If a group
+ contains more members, the reply would include an
+ AD-specific range extension. This option disables
+ parsing of the range extension, therefore large
+ groups will appear as having no members.
