useradd: Unknown group

[Herta Van den Eynde]

/etc/default/useradd defines what default values will be used when 
adding a user.  If you want every user to be in the groups 'dialout, 
uucp, video, audio', then evidently, you should first create these 
groups.  If you don't want these groups assigned by default, simply 
remove them from the file.  FWIIW, none of my systems have a GROUPS 
definition in /etc/default/useradd.

Since noone is using the pncerts group at the moment (there are no user 
ids following the last colon), let's start from a clean situation:

# userdel rrao
# groupdel pncerts
# groupadd -g 1001 pncerts
# useradd -m -d /home/rrao -s /bin/bash -g pncerts -u 1011 rrao

Kind regards,

Herta
