Why are dots in username & groupname no longer allowed?
For some strange reason I am no longer able to create groupnames or
usernames (with useradd and groupadd) that contain a dot.
Uptill now it was possible to create user&groupnames like c.smith but now
I get these errors:
[root at server etc]# useradd c.smith
useradd: invalid user name 'c.smith'
[root at server1 etc]# groupadd c.smith
groupadd: c.smith is a not a valid group name
