Can someone please tell me how to LDAP query the ADs to check if a particular user is a member of a particular security group object. The security group object members may have nested members via other security groups...<BR><BR>Example..<BR><BR>[Security Group A]<BR> Members User1, User2, User3, Group1, Group2, Group3<BR><BR>Group 2 contains GroupX<BR><BR>The user is a member of Group X<BR>
