We are set up to use kerberos for authentication so the config line 
has to remain the same.

It was pointed out to me in another post that I needed a correct 
/etc/krb.conf file (like I said I am new to afs/kerberos). Putting 
that file in place now allows me to authenticate but I am not getting 
a token (see my other post).

What I am trying to figure out is:

If kaserver uses udp 7004, how is it that when I successfully login, 
sshd in debug mode reports that it is using the default port udp 750?
