Attempts to create an account:
Checking input data......Done WWWAcct 12.0 (c) 1997-2007 cPanel, Inc.......Done Running pre creation script (/scripts/prewwwacct)......Done Adding User...Unable to add group deuce
The script actually manages to create the group, which can be verified in /etc/groups.
# cat /etc/group --- deuce:x:32070:
Which you have to manually remove to get the script to work again.
# /usr/sbin/groupdel deuce
As mentioned in the above post, (paraphrasing the Cpanel techs) the problem was that nscd is running.
# /sbin/service nscd stop
Account gets created without a hitch (assuming that group is removed manually). Easily reproducible.
