Description David Lehman 2005-05-27 18:21:40 EDT
Description of problem:
s-c-users doesn't allow '.' in user/group names for new accounts. useradd does.
Please sync them up so people get consistent behavior. Here's what I think is
useradd's *intended* behavior:

* Wed Oct 27 2004 Adrian Havill <havill@redhat.com> 2:4.0.3-23.04
- conform to posix for user/group name input checking [def 3.426
  and 3.189] which is posix portable filename character set [3.276]
  while disallowing dash for first char as recommended, and disallow
  dollar sign)

NOTE: The above is from RHEL3 branch and was broken in the next shadow-utils; I
hope that was not a change of mind but rather an error.

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

How reproducible:

Steps to Reproduce:
1. create a user in s-c-users containing '.' (eg: "joe.schmoe")
Actual results:
s-c-users won't let you do it ("Please do not use punctuation in the user name.")

Expected results:
It should work according to POSIX.

NEEDINFO_PM has been deprecated. Changing status to NEEDINFO and changing
ownership to pm manager.
Comment 9 Daniel Riek 2006-03-13 13:54:44 EST
This would not have needed PM ACK as it is categorized as a bug.

A fix to this issue seems to be available and it is not unlikely that this
component will be included in a future Update release. 

Moving to the next Update, clearing all ACKs.
