Patch to add username with dot support to shadow-utils none

Description Sebastian Stelmasik 2004-02-13 12:39:43 UTC 
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 
http://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=115383

Patch to add username with dot support to shadow-utils

Here is a small and simple patch for usernames with dot support in shadow
utils.
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
Comment 2 Eido Inoue 2004-10-13 14:54:24 UTC 
we now allow dots (and mixed case), but not other puctuation.
