I would appreciate it if the GSSAPI patch could gain an option to pass
in GSS_C_NO_CREDENTIAL into gss_accept_sec_context or GSS_C_NO_NAME
into the server side call for gss_acquire_credentials.


This combined with the 1.3 code should solve the multi-homed hosts
problem nicely.  The 1.3 code will accept any principals in the keytab
in the GSS_C_NO_NAME case.  Note that if you use this option, you as
an administrator must take care to make sure only principals trusted
for host authentication are allowed in /etc/krb5.keytab.
