Description of problem:
grpck does not handle large groups
Version-Release number of selected component (if applicable):
Steps to Reproduce: (untested procedure)
1. create a new group
2. add lots of users until the line in /etc/group is longer than ~30000 characters
3. run grpck
4. grpck has truncated the line and so possibly truncated a user name. The
truncated user does not exist and grpck wants to remove the user
Other tools support groups this large so grpch should also.
I did some further digging and found the problem. It was actually our gshadow
file. It does have corruption but it was caused by 2.1AS and not EL4. grpck was
actually doing the correct thing. Sorry about the false report.
