I have made a "strace useradd eric" and I have attached the output (during a
script session).

Comment 4 Peter Vrabec 2006-05-11 12:50:00 UTC
Is there a group with ID 100 on your system? 
grep 100 /etc/group 

Comment 5 Joachim Backes 2006-05-11 12:58:55 UTC
No, only a group with groupid 1000.

Comment 6 Peter Vrabec 2006-05-11 13:06:52 UTC
So, that's the problem. 
Change your default group in /etc/default/useradd 
create group with ID=100 
see: man useradd  
section default values 

Comment 7 Joachim Backes 2006-05-12 04:59:07 UTC
You are right, but if I use the useradd command together with the "-g <some
existing group>" option, then the warning about not existing gid 100 appears
too, and I think this is a bug. 

Comment 8 Peter Vrabec 2006-05-12 15:29:40 UTC
but the user is created. I don't consider this as a bug. You can try to report 
it to upstream.
