  That's good...

  Why not just use the features that come with the server?  It supports querying AD for group membership via LDAP-Group:

	if (LDAP-Group == "admin") {
		... do stuff ...

  The LDAP group checks are even cached, so it doesn't hit AD every time you do the group comparison.

  I wouldn't recommend that.

  Instead, please explain what that script does, and why you need it to return almost 100 group.  I'm willing to bet that you can re-implement that functionality in FreeRADIUS.
