I emailed the gssapi patch maintainer.

anymore. It's "now" as of perhaps 5 years ago. 3.5 doesn't
have the GSSAPIAuthentication stuff, but 4.3 does, so it was
added somewhere in between (I didn't bisect any further).
The second paragraph on the web page ("Larger sites...") cites why the
patch is still useful.
I let Simon know that his latest patch set...
... does not apply cleanly to 5.6p1.
He may refresh that patch (it's only slightly broken), so I think it
will be useful to just mark it BROKEN for now. We can always
remove it later.
We can even deprecate the option, but right now bsd.ports.mk doesn't
really support deprecating individual options so just adding some text
to that effect to the BROKEN string may be the best option I am aware
of. I CC'd ports@ - maybe someone there knows of some precedent in this
Unfortunately, there's really no way of knowing how many people will
be disappointed if the GSSAPI option disappears.

The now is OpenSSH for about the last 5 years. OpenSSH includes GSSAPI
user authentication, but not GSSAPI key exchange. User authentication
is useful until you have more than 5 or so machines on your site,
beyond that, virtually every large organisation that I'm aware of with
Kerberos deployed is using OpenSSH with GSSAPI key exchange.

The patch as given on my website is all applicable to 5.6p1. In
addition to supporting key exchange it also supports cascading
credentials upon renewal, which is useful if you have a chain of many
ssh connections from your desktop machine.
