path = /srv/smb/hidden write list = user
create mask = 0700 directory mask = 0700 [%confidential]comment = hidden share path = /srv/smb/hidden write list = user create mask = 0700 directory mask = 0700 [confidential$]comment = hidden share

10.

How must Samba be configured so that it can check passwords against the ones in /etc/passwd and /etc/shadow?

Set the parameters "encrypt passwords = yes" and "password file = /etc/passwd". Set the parameters "encrypt passwords = yes", "password file = /etc/passwd" and "password algorithm = crypt". Delete the smbpasswd file and create a symbolic link to the passwd and shadow file. It is not possible for Samba to use /etc/passwd and /etc/shadow directly. Run smbpasswd to convert /etc/passwd and /etc/shadow to a Samba password file.
