[Freeipa-users] Very Odd Fedora 21 Auth Issue (Server: IPA 4.1.0)

[craig.redhat at shakenautomotive.com.au]

Hi, 
This is one odd issue?!

Red Hat Enterprise Linux 7.1

#Server Side
Red Hat Enterprise Linux Server release 7.1 (Maipo)
ipa-server-4.1.0-18.el7_1.3.x86_64

#Client side
Fedora release 21 (Twenty One)
* freeipa-client-4.1.4-1.fc21.x86_64
* sssd-client-1.12.4-3.fc21.x86_64


Issue:
User cannot login to their PC 

Error: /var/log/secure
Jun 23 17:08:48 johnpc sshd[3591]: pam_unix(sshd:auth): authentication
failure; logname= uid=0 euid=0 tty=ssh ruser= rhost=localhost  user=john
Jun 23 17:08:48 johnpc sshd[3591]: pam_sss(sshd:auth): authentication
failure; logname= uid=0 euid=0 tty=ssh ruser= rhost=localhost user=john
Jun 23 17:08:48 johnpc sshd[3591]: pam_sss(sshd:auth): received for user
john: 7 (Authentication failure)

However:
1. Kerberous works;
kinit john 
john at johnpc /etc/pam.d> klist
Ticket cache: KEYRING:persistent:365:365
Default principal: john at EXAMPLE.EXAMPLEAUS.COM.AU

Valid starting     Expires            Service principal
23/06/15 16:49:30  24/06/15 16:49:28
krbtgt/EXAMPLE.EXAMPLEAUS.COM.AU at EXAMPLE.EXAMPLEAUS.COM.AU

2. LDAP works;
john at johnpc ~> getent passwd john
john:x:365:132::/home/john:/bin/bash

3. ssh to IPA server works with a password (so not relying on the kerberous
ticket);
john at erio ~> ssh john at sysvm-ipa1
john at sysvm-ipa1's password:

Any advice would be greatly appreciated?
