Description of problem:
If kerberos support is enabled, users that have a longer username than 9 chars
can not log in... even root can not su - to that user account.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Install RH73 with kerberos support or upgrade RH72 system that had kerberos
2. create an user that has username longer than 9 chars (adduser u234567890)
3. set a password for that user (passwd u234567890)
4. ftp 0 (username: u234567890 ) - it will fail
5. su - u234567890 - it will fail as well
Actual Results: Invalid password
Expected Results: Successful login.
This bug came in when I upgraded from 7.2 to 7.3.
During some period I used kerberos, than I turd off the kdc etc kerberos
services, and the system was working perfect.
But after the upgrade not even one user with longer username could log in.
- in authconf remove kerberos support.
