The only difference I know about is that the users who CAN change their passwords have not got an expired password (so they can login and use kpasswd from the shell), whereas those who CANNOT change their password need to reset it before logging in (i.e., they get the 'your password has expired, reset it now etc etc). I updated the kerberos libraries/tools on the CentOS 6.0 box using the Continuous Release repository, and then edited the ldap configuration to get around https://bugzilla.redhat.com/show_bug.cgi?format=multiple&id=713525 and users can now reset their passwords on that box during login and on the shell (kpasswd). I'm not sure which of these actually fixed the problem (if any). I'll continue to keep an eye on it for now. It may be as you say, a version difference, although I'm unaware of any large differences in versions between the machines, is kerberos very sensitive to version changes? > > If you can get a packet capture of a client request, we can examine the > first few bytes to check what's triggering the failure. > tcpdump says its a V5 packet. I have captured the entire login/reset failure and can email it to you directly if you wish.
