Chapter 22. Samba
• Share — Samba users do not have to enter a username and password combination on a per
Samba server basis. They are not prompted for a username and password until they try to
connect to a specific shared directory from a Samba server.
• User — (Default) Samba users must provide a valid username and password on a per Samba
server basis. Select this option if you want the Windows Username option to work. Refer to
Section 22.2.1.2, "Managing Samba Users"
• Encrypt Passwords — This option must be enabled if the clients are connecting from a system
with Windows 98, Windows NT 4.0 with Service Pack 3, or other more recent versions of Microsoft
Windows. The passwords are transfered between the server and the client in an encrypted format
instead of as a plain-text word that can be intercepted. This corresponds to the encrypted
passwords option. Refer to
encrypted Samba passwords.
• Guest Account — When users or guest users log into a Samba server, they must be mapped to a
valid user on the server. Select one of the existing usernames on the system to be the guest Samba
account. When guests log in to the Samba server, they have the same privileges as this user. This
corresponds to the guest account option.
After clicking OK, the changes are written to the configuration file and the daemon is restart; thus, the
changes take effect immediately.
22.2.1.2. Managing Samba Users
The Samba Server Configuration Tool requires that an existing user account be active on the
system acting as the Samba server before a Samba user can be added. The Samba user is
associated with the existing user account.
