The need to disable the mutual auth is the only part of this that has
not now been committed.

The setup uses Heimdal from lorikeet, with manually setup keytab entries
in /etc/krb5.keytab.  I'll soon (tomorrow) change this to use an in-
memory keytab.

With the changes I made tonight, I have made much more progress - we now
get a full login, apparently using Kerberos for 'most' of the process.  

We see the client fall back to NTLMSSP for some of the later stages of
the login, which may be related to us not accepting Kerberos for the
DNS/ name.  I need to allow all the different aliases for HOST/ in the
servicePrincipalName search.

I expect as we keep filling out more of the puzzle, that the fallback
point will keep being pushed back.  These are exiting times indeed!
