Below is the terminal execution
[root@machine chef-server]# useradd -s '/bin/sh' -d '/opt/chef-server/embedded' -r chef_server
useradd: Can't get unique system GID (no more available GIDs)
useradd: can't create group
[root@machine chef-server]# uname -a
Linux machine 2.6.39-300.20.1.el6uek.x86_64 #1 SMP Mon Nov 12 04:30:55 PST 2012 x86_64 x86_64 x86_64 GNU/Linux
What is preventing the group creation?
The command is generated by Chef server reconfigure command and i don't have any control on it.
