Below is our standard krb5.conf:
------
# $Id: krb5.conf 143 2011-12-29 21:03:39Z tm707 $
[logging]
 default = FILE:/var/log/krb5libs.log
 kdc = FILE:/var/log/krb5kdc.log
 admin_server = FILE:/var/log/kadmind.log

[libdefaults]
 default_realm = EXAMPLE.COM
 dns_lookup_realm = true
 dns_lookup_kdc = true
 # XXX: Match AD domain default
 ticket_lifetime = 10h
 forwardable = yes

[realms]
# XXX: Not necessary due to DNS lookups enabled above.
# EXAMPLE.COM = {
#  admin_server = ldap.example.com:749
# }

[domain_realm]
 example.com = EXAMPLE.COM
 .example.com = EXAMPLE.COM

[appdefaults]
 pam = {
   debug = false
   ticket_lifetime = 36000
   renew_lifetime = 36000
   forwardable = true
   krb4_convert = false
 }
------

And the following lines were added in the system-auth pam.d file.
------
auth        sufficient    pam_krb5.so use_first_pass
account     [default=bad success=ok user_unknown=ignore] pam_krb5.so
password    sufficient    pam_krb5.so use_authtok
session     optional      pam_krb5.so
------

Additionally, make sure no /etc/krb5.keytab file exists.  Typically our
hosts are joined to AD but I just removed my test box from the domain
and it still works fine once I also removed the keytab file.
