PAM, sshd and RSA does not work together!

[Roman]

Hi there,

we are running a Suse 8.1 Linux file server and would like to connect to 
it through SSH via the public key mechanism (RSA) from our Windows2000 
clients.
Connecting to the linux box with the user/password mechanism just works 
fine, but the pubilc key mechanism fails.
What I have found so far is (from syslog), that sshd calls PAM which 
accepts when verifing the password but denies with the RSA.

I read the PAM manual page and still have not figured out what to change 
in /etc/pam.d/sshd to get it working.

Where do I get information on what the different libraries exactly do 
and do I need a special library to make SSH RSA work?
Can anyone provide a sample configuration for sshd that work for 
password and RSA login?

Here is the syslog  ...

and the sshd configuration file:

session  required       pam_unix2.so    none # trace or debug

I would appreciate some help.
