I am not sure the above messages are from your
ssh... And I know nothing about configuration with Free Radius or
Kerberos, so your problems may be completely different from ones
I've had but...
I take it you are running ssh on the Win7 workstation and trying to
login to the linux samba server.
if your username in the domain is 'user' (i.e. you are 'domain\user'),
and your linux account is 'user',
then on the ssh line, you might try
'ssh user at linux-server' instead of the "normal" 'ssh linux-server'
If that works, then your 'sshd' server on your linux server
is probably receiving 'domain\user' as the username, (not just 'user')
and doesn't know what to do with that.
Theoretically should be resolvable via proper pam and config files
(all the file ops map my 'domain\user' => 'user' on the PDC), but,
a _*hack*_ I use (but would find a better solution in a production
environment) is to create a 2nd /etc/passwd & /etc/shadow entry
that dups my 'user' but has the username field changed to 'DOMAIN\user'.
(getting the capitalization to agree with what the workstation think's
it is, is important in this case; upper case is norm, so unless you've
customized things in the win registry, shouldn't be a prob (not that I
would have any knowledge of this, of course...)....
But I'd try to get 'winbind' config'ed with pam to map the username
properly for a best fix (on my 'todo list') ... just hasn't
been that important ...
Best short term:
specify the username with the hostname when using the 'ssh' (or scp,
i.e. 'scp file user at remote:/tmp' ) ...
In any event, using kerberos/freeradius, there should be some way
to make sure that a 'domain\user' is mapped to 'user' on a PDC...
Or it might be the 'ssh' client that "shouldn't" be prepending the
windows domainname.... not sure.
But hopefully gives you some ideas where to look...
