s/key

[spc]

Hello

Can someone tell me, how to enable s/key auth via OpenSSH ?
I tried to enable ChallengeResponseAuthentication yes in sshd_config
and SkeyAuthentication yes 
ChallengeResponseAuthentication yes in ssh_config
As i can read in man:
-v      Verbose mode.  Causes ssh to print debugging messages about its
             progress.  This is helpful in debugging connection, authentica-
             tion, and configuration problems.  The verbose mode is also used
             to display skey(1) challenges, if the user entered "s/key" as
             password.
But i don't see anything about s/key there..i tried to enter s/key password
and it don't work too. S/key is working properly as i can see in ftp for
example..Any help will be good.

Best Regards
