Passwords#

The samba password is not the Linux password.

The Microsoft SMB Protocol originally used plaintext passwords. Starting with Windows 2000 and Windows NT 4.0 with Service Pack 3 or higher required encrypted Samba passwords. To use Samba between a Linux system and a system with Windows 2000 or Windows NT 4.0 Service Pack 3 or higher, you can either edit your Windows registry to use plaintext passwords or configure Samba on your Linux system to use encrypted passwords. If you choose to modify your registry, you must do so for all your Windows NT or 2000 machines — this is risky and may cause further conflicts.

Using LDAP, the password is from sambaLMPassword or sambaNTPassword. The samba password must be set independently from the Linux and the LDAP password.

In a Windows Domain, authentication process performed from a Domain controller.

In contrast, Linux and (most) Unix variants allows authentication redirection where the the authentication process can be performed from by a "Pluggable Authentication Module" (PAM).

Setting the samba Password#

The samba password can be set or changed for the current user with: 

 smbpasswd

Troubleshooting#

Note: This is from our samba install that is LDAP enabled.

Testing from Linux#

Commands from a Linux workstation that may help.

Get the Domain SID#

net getlocalsid willeke
SID for domain willeke is: S-1-5-21-852355746-2165432268-4188094699 (sid shown is fake)

Start Samba Services#

rcsmb restart
rcnmb restart

Add samba users#

First we need to give Samba the admin password. This is accomplished with: 
smbpasswd -w somethingverysecret
where somethingverysecret is the password for the account you set in smb.conf. (Tip: if you put a space at the start of the command line then the command won't be saved in you shell history)

You should see a line that says "Setting stored password for 'cn=admin,o=sbs' in secrets.tdb" That will give Samba access via LDAP, so we should now be able to add user accounts.

Noraml Users #

smbpasswd -a jim
and enter the password twice when prompted

You should see a line that says "Added user jim". If you get error messages complaining about ldapsam_search_one_group you can safely ignore them! The user should now able to log in via Samba.

Test samba connectivity#

You can use a windows machine here if you like, but it's easier to test thing on Linux first. The command smbclient allows you to test samba without leaving the command line!

Try 

 
smbclient //francis/home/tv -U tv
and enter your password when prompted. You should get a prompt like smb: \>
