If I logon using domain credential in ssh or console there are no authentication problem but if I use kdm in /var/log/kdm.log I found:

The XKEYBOARD keymap compiler (xkbcomp) reports:

Errors from xkbcomp are not fatal to the X server

but in /var/log/auth.log all seems to works:

Aug 28 09:14:25 notetentoni kdm: :0[3930]: pam_winbind(kdm:setcred): user 'DOMINIOCSA\psala' OK


I'm not sure is a bug of kdm any way the problem arise if I use kdm as login manager

have a great day
