More on kadmin client crash

[Leif Johansson <leifj@matematik.su.se>]

I investigated further and found that neither the client nor the server
seemed to call krb5_auth_con_init. I added the calls (at what looked 
like apropriate places in the code based on tcp_{server,client}.c).
However kadmin still crashes. Now at this place:

This seems to indicate that the auth_context has neither local_subkey,
remote_subkey or keyblock (which is what gets stored) in the "key"
variable. Reading krb5_mk_priv there is one of those "XXX" which 
must mean that the jury is still out on that piece of code. Hope this
helps.
