I kind of did.  The Annexes I have sort of do Kerberos -- they'll get a TGT
from a server as a method of password checking.  They don't, however, use that
TGT *for* anything -- which means I can have all my users log into the Annex,
and then trust the Annex with hosts.equiv, but I'm not very comfortable about
that idea.

Since the Annex already *has* a filesystem, it would seem to me that Xylogics
must already have done most of the hard part of porting K4 to their box.  I
don't really understand why they didn't Do The Right Thing, and though it's my
only substantial gripe about the Annex, I do wish they'd go fix it posthaste.

There aren't a lot of fully-featured terminal servers out there that do
support Kerberos.  I know about Ciscos and Xyplexes, but I have a whole host
of reasons for hating them, and even if I'd ever go near a Livingston
Portmaster again (which I won't -- some good ideas and an awful murder --
oops, I mean execution) they don't support it either.  

But yes, I could sort of use Kerberos on my terminal servers now, and I expect
to use it on them one way or another soon.  But not everyone can or will, and
I still think S/KEY support is a better solution as it doesn't require
waiting on terminal server vendors to ge things done.

After all, where can I find a terminal server that does Kerberos 5?
