This looks like a client-side problem. Is the client also running some version
of SuSE? At this point I would look at the source code for the MIT Kerberos
package (the exact version installed on your client) and work out what must
have been happening. Running the ssh client under valgrind may also prove
instructive. Does your ccache contain a ticket for host/geronimo.creedon.biz
after the error?
