Problems with Keytabs

[js1]

I get the following message when I run "kinit -k -t my.keytab":

  kinit(v5): Cannot find KDC for requested realm while getting initial credentials

It works fine if I just do "kinit my_user".  I did a tcpdump and noticed
that when I try to use the keytab, kinit seems to look for 
_kerberos._udp.LOCALDOMAIN and _kerberos._tcp.LOCALDOMAIN.  But, 
when I don't use the keytab, it queries my kerberos server, 
kerberos.mydomain.bogus.  How do I alter this behavior?  Thanks for
any tips.
