Our ticket cache location is somewhat random on each login, but it can
always be reliably found by looking at the environment variable
KRB5CCNAME. I can specify the temporary location, but it would be much
better to somehow be able to grab the auth info from that.
I got this working after a few attempts and reading up on Java auth
configs. It looks like I have to have the line which tells which user
to use, i.e.
props.setProperty("user", "koczan");
...but it has to be the same as the user/principal in the ticket
cache. It would be nice in the case of web scripts or cron jobs (where
things may run as different or arbitrary users) if I could specify
that elsewhere without having to recompile. I tried specifying the
principal in the config file, and I tried specifying the user on the
command line with -D, but neither worked without the setProperty line
in the .java file.

Still, this is a lot further along compared to where I was a week ago.
Thanks again.
