What does "ssh -v usern...@`hostname`"provide? and is hostname the same as the 
host principle you set up? SSH -v will tell which ones its trying at least.

Ok, using the correct hostname, the same thing happens:

[r...@ipa01 ~]# ssh mrow...@`hostname`
[email protected]'s password:
Last login: Mon Dec 15 18:42:09 2008 from localhost.localdomain

**Trying to log in with a valid ticket, but asks for password
[mrow...@ipa01 ~]$ ssh mrow...@`hostname`
[email protected]'s password:

**Shows that there is a ticket
[mrow...@ipa01 ~]$ klist
Ticket cache: FILE:/tmp/krb5cc_502_WaiNgJ
Default principal: [email protected]

Valid starting     Expires            Service principal
12/15/08 19:52:10  12/16/08 05:52:10  krbtgt/[email protected]
        renew until 12/15/08 19:52:10


Kerberos 4 ticket cache: /tmp/tkt502
klist: You have no tickets cached

**Showing the kerberos realm is the same as the ssh¹ed hostname
[mrow...@ipa01 ~]$ cat /etc/krb5.conf
...
[realms]
 IPA.COMCAST.COM = {
  kdc = ipa01.security.lab.comcast.com:88
  admin_server = ipa01.security.lab.comcast.com:749
  default_domain = security.lab.comcast.com
  database_module = openldap_ldapconf
 }
...
