Upgrade krb5 to centos 5.6 breaks samba4?

I just did a yum upgrade to the latest Centos 5.6 and it appears that 
something broke in my kerberos setup for Samba 4.  I'm getting the 
following error in the samba logs:

/usr/local/samba/sbin/samba_dnsupdate: RuntimeError: kinit for 
RHTEST01$@ETI.COM failed (Cannot contact any KDC for requested realm: 
unable to reach any KDC in realm ETI.COM)

I've verified that my /etc/krb5.conf is still in tact (not overwritten 
by the updates.  Here's what I have:
[root at rhtest01 var]# more /etc/krb5.conf
     default_realm = ETI.COM
     dns_lookup_realm = true
     dns_lookup_kdc = true
     ticket_lifetime = 24h
     forwardable = yes

     ETI.COM = {
         kdc = rhtest01.eti.com:88
         admin_server = rhtest01.eti.com:749
         default_domain = eti.com

     .eti.com = ETI.COM
     eti.com = ETI.COM

Can anyone make any suggestions as to what might be wrong?
