Hi, When using mswin_check_ad_group.exe 1.x in global mode (-G options), the check is done always against a global group placed in the user's domain. Starting from 2.7 STABLE 8, mswin_check_ad_group.exe 2.x is now a full AD group helper supporting full forest wide group recursion. Take a look to the included docs for details.
