The server is a NT 4.0 domain member server. It uses Winbind. Everytime I login to the system using system local user, such as root, it says this: [2004/04/21 11:01:39, 1] nsswitch/winbindd_group.c:winbindd_getgroups(954) user 'root' does not exist Everytime I tried to switch to another local user, such as "su bb", it would say in /var/log/messages: [2004/04/21 10:59:15, 1] nsswitch/winbindd_group.c:winbindd_getgroups(954) user 'bb' does not exist Is this a normal behavior? Or is there any setting that would turn these messages off? Thanks, Hai
