   I'm getting an error from cvs.  I use kerberos.  I've gotten this
   before but I forgot what it means and how it was fixed.

   creche. cvs update -A
   cvs: ../../../devo/cvssrc/src/client.c:3937: connect_to_gserver: Assertion `need <= sizeof buf' failed.


   Any clues?

This started happening to me too, so I looked at it.  The CVS server
on sourceware is printing
    cvs [pserver aborted]: could not acquire GSSAPI server credentials

This means that the gss_acquire_cred function run by the CVS server is
failing.  I believe this means that the cvs/egcs.cygnus.com ticket has
disappeared from the Kerberos database, or that it has disappeared
from the ticket file on sourceware.

I took a look at /etc/v5srvtab.  I see that it has an entry for
cvs/sourceware.cygnus.com.  I've never quite followed the
canonicalization strategy for Kerberos.  However, my vague
understanding is that Kerberos will canonicalize the host name.
Currently the canonical name for the sourceware machine is
egcs.cygnus.com.  Is there any chance that this changed recently?  Was
the canonical name sourceware.cygnus.com until recently?  If it was,
then the fix is to change the canonical name back to
sourceware.cygnus.com.

If that did not change recently, then somebody who knows the
CYGNUS.COM Kerberos administrator password needs to confirm that the
cvs/sourceware.cygnus.com Kerberos ticket still exists, and that it is
version number 2.
