I'm running into a problem - the FreeBSD openssh-portable w/GSSAPI patch
doesn't appear to be working the way I'd expect it to.

I modified the /usr/local/etc/ssh/sshd_config on athena (a currently
working Kerberized server) to include:

 KerberosAuthentication yes
 KerberosTicketCleanup yes
 GssapiAuthentication yes
 GssapiKeyExchange yes
 GssapiUseSessionCredCache yes

and ran /usr/local/sbin/sshd on port 8022 (so it wouldn't conflict with
the existing sshd). Here's what I tried to test it:

1. Ran a k5destory and a k5list to confirm that I did not have a ticket

2. Ran '/usr/local/bin/ssh -2 -p 8022 localhost' ... oddly, I got a
   password prompt that only took my system (rather than Kerberos)

3. Ran k5list to see if I had a ticket created - I didn't

I then tried grep'ing (with -i) for 'kerb' and 'gss' in the source tree
to see if anything stood out, but I didn't see anything noteworthy. I
suspect I'm missing some obvious steps somewhere. Can someone post a
working sshd_config or point our any errors I have?

Thanks muchly,
