this is what I found:

# net groupmap list | grep -i admin
Domain Admins (S-1-5-21-3..-...-...-512) -> Domain Admins
Administrators (S-1-5-32-544) -> Administrators

# getent group | grep -i admin
Domain Admins:*:512:root,user1,user2
Administrators:*:544:user1,user2

# getent group | grep -i root
root:x:0:
Domain Admins:*:512:root,user1,user2

Anyway - why does the process faster for admin users?

I'll try this later - I need remote access for a desktop client.
