Edit /etc/samba/smb.conf and add set the basic settings in the 'global' section. The only important item is the "security=user" option.
The important thing is to enable the samba users with:
# smbpasswd -a
which adds (-a) a new user to the samba user database, and sets a new password to it.
Not doing this causes a 'permission denied' error in the client when attempting to mount it.
The syntax to mount a samba share is:
# mount -t cifs -o user=
In the /etc/samba/smbusers file, it is possible to map sambe user names to UNIX user names, but it is not required to do so. By default, samba does a one-to-one mapping.
If we want to announce the samba shares on the network, it is necessary to start the 'nmb' service. Use the normal chkconfig interface to start smb and nmb on startup:
# chkconfig --add nmb
# chkconfig --level 3 nmb on
# chkconfig --level 4 nmb on
# chkconfig --level 5 nmb on
