System: OSF1 kangaroo.mit.edu V3.2 214 alpha
Machine: alpha
I was trying to run the rpc tests on the alpha and they failed.
It appears that the server program fails "unable to set gssapi names"
Tracking down into the code - the error is
GSS-API authentication error acquiring credentials: Miscellaneous failure
GSS-API authentication error acquiring credentials: No principal in keytab match

The problem stems from the fact that the keytab has:
server/KANGAROO.MIT.EDU@SECURE-TEST.OV.COM

but the code is looking for
server/kangaroo.mit.edu@MIT.EDU


Note - the casing problem.

I would guess that the procedure creating the keytab is doing
something funky. Acually, I just found it:
qualname.pl on kangaroo returns KANGAROO.MIT.EDU
on dcl returns dcl.mit.edu

We need to downcase this string!!!

gmake check
When I find my perl book I will remember how to downcase the
qualname.

That's interesting. One would expect that qualname.pl and the gss-api
libraries are both using the same method to obtain the FQDN:
gethostbyname, followed by gethostbyaddr. Why is one returning an
upper-case result but the other returning a lower-case result? We
should find the answer, because if we don't it may bite again later.

Looking at the code in gssapi/generic/util_canonhost.c:
(which is the only use of gethostbyname in the gssapi code).
g_canonicalize_host(hostname) does a gethostbyname, gethostbyaddr, and
then lowercases the string. So, therefore, qualname.pl was not doing the
same as the gssapi code. (My problem now is determining who is the user
of g_cacnonicalize_host....)...
