my query is -> 
memberOf=CN=VPN-Users,CN=users,DC=internal,DC=external,DC=com

Users who will be allowed access to the VPN are assigned to a security 
group
named "VPN-Users".  I then used Softerra's ldapbrowser 
(www.ldapadministrator.com)
to look at one of the users in the group and pulled the syntax for the 
"memberof"
attribute that listed the VPN-User group.

I would expect the extend query to validate a user who is a member of 
the VPN-Users group.
