I see that in /etc/ssh/ssh_config I have the above setting
in both Fedora-19 and CentOS-6.4 .
In both cases ssh (openssh) tries and fails to use gssapi-with-mic
authentication, with the message
=======================
Unspecified GSS failure.  Minor code may provide more information
No Kerberos credentials available
=======================
It then goes on to use publickey authentication, successfully.

As far as I can see, this is because openssh has over-ridden
the default
  #   GSSAPIAuthentication no
with
        GSSAPIAuthentication yes

I've googled for this, and see that some people recommend
reverting to the default No.
But I assume openssh has some reason for making this change.

What would I do if I actually wanted to use GSSAPIAuthentication?
