Description P Fudd 2005-05-15 16:39:12 EDT

From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.3) Gecko/20040922

Description of problem:
useradd goes into an infinite loop if you try to add someone to a supplemental group that appears twice in the group file.

Version-Release number of selected component (if applicable):
shadow-utils-4.0.3-37

How reproducible:
Always

Steps to Reproduce:
1. echo dupgroup:x:505: >> /etc/group
2. echo dupgroup:x:506: >> /etc/group
3. /usr/bin/seuseradd -G dupgroup someuser
 

Actual Results:  Stuck in infinite loop, syslog messages being generated rapidly.

Expected Results:  Either quit with error message or add to the first group.

Additional info:

This bug report is the product of a painful elimination process.
