Thank you onebuck for your greeting and answer.
Of course I'll go to howtoes, but just for now one more question.
With samba conf - ok, due to you that's clear for me now (I do remember browseable parameter but didn't have time to experiment with it).
But, regarding permissions.... Do you mean that for them not to be accessible (in the way like \\server\account), I need to change permissions for all the folders that are homes in /etc/passwd (I mean only system accounts like bind, dovecot etc).
Once again thanks for future answers!
