*] To Kevin
I tried :
$> ssh WINDM+nicola
But that does not solve, in this case the user is not recognized.
------- sshd output ------------
...
debug3: mm_answer_authpassword: sending result 0
debug3: mm_request_send entering: type 13

------------------------------------
Supplementary information:
*] Forcing user/password authentication does not work
$> ssh -o PreferredAuthentications=password -o PubkeyAuthentication=no
nicola@domus

--------------------------------------
*] The only thing that works is logging in as the 'cyg_server' user.
But that defies the whole purpose to define such user.
$> ssh cyg_server@domus
