Glad to help.

For the record, I did misspeak in my earlier note.  I said,

>> The Kerberos libraries do a gethostbyname(gethostbyaddr()) of the IP
>> address of the server host to figure out the host service principal name.

But I had it somewhat backwards.  I should have said something like this:

   The Kerberos libraries do a gethostbyaddress(gethostbyname()) of the
   application server hostname as requested by the client.

So that, for example, gethostbyname( gives ''.
And, on your system as it was configured, gethostbyaddr( would
return just 'citest'.
