But compaired to his starting smb.conf that was not a "default" settings. 

What i think is also very interesting and is related to. 
Number of users / winbind enum users
Number of groups / winbind enum groups
Number of computers / ? 
How many groups are in groups and whats the max depth of the nested groups. / winbind expand groups = 

Win Clients, XP/Vista/Win7/8/8.1/10 ? 
Linux/Unix clients ? 

Very valueble info for the devs i think. 

Greetz, 

Louis
