UNIX Samba: Make A Share Writable

How do I make a Samba share writable under UNIX / Linux operating systems, especially all home directories for respective users?

By default, the home directories and other share are exported read-only or configured as read only. Change the "read only" parameter to 'no' if you want to be able to write to them via other CIFS clients.

Configuration

Edit /etc/samba/smb.conf, enter:
# vi /etc/samba/smb.conf
Fine [Home] share configuration and update it as follows (note wriable is set to yes):

[homes]
        comment = Home Directories
        browseable = yes
        read only = no
        writable = yes
       valid users = %S
       valid users = MYDOMAIN\%S

Save and close the file. Restart samba server:
# /etc/init.d/samba restart
OR if you are using RHEL specific distro, enter:
# service smb restart
