Description Sebastian Stelmasik 2004-02-13 07:39:43 EST
From Bugzilla Helper:
User-Agent: Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1) Opera 
7.23  [en]

Description of problem:
useradd can not handle usernames containing punctuation and 
usermanagement crushes if You enter a user manualy into 
passwd/group/shadow with a segmentation fault even if You delete the 
user from this files - so I'll have to reinstall the system...
I can no longer add or delete ANY user
I was migrating users from Redhat 7.3, when this problem occured.
I think it's the same bug as 

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1.useradd "some.user"
2.enter a user manually

Actual Results:  1: useradd: invalid username
2: useradd: segmentation fault

Expected Results:  user some.user should have been created

Patch to add username with dot support to shadow-utils

Here is a small and simple patch for usernames with dot support in shadow
I tested it and it seems to work... apply it on shadow-utils source dir with
-p0, file to be patched is libmisc/chkname.c

we now allow dots (and mixed case), but not other puctuation.
