Description of problem:
The patch given in bug ID #17847 does its matching with regard to case, so it is
unlike the behavior of the old SSH that the function was take from. SSH
converted hostnames to lowercase before doings its matching.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. add entry in hosts.allow for MiXeD-CaSe domain name using * or ?
2. observe failure to match the host
Actual Results: May 14 14:30:00 host sshd: refused connect from
Expected Results: connection should be allowed as though the hostname had been
specified without wildcarding
I added a comment to bug ID #17847, but that's marked as closed, so I created a
new bug ID.
Should be fixed in 7.6-22 or higher.
