smbpasswd

I am trying to set up Samba on a recently installed Debian platform (current stable release, everything apt-get upgraded recently) and am having a host (no pun intended) of problems.

The immediate problem is that I am unable to establish a Samba user password on the local machine, which means I can't mount any samba shares on this machine to any other machine, since it won't authenticate the user without a password, which I can't set. (I'm using security = user in smb.conf).

Smbpasswd executes, prompts for the old and new passwords, etc., but then fails with the following error message:

Quote:

Could not connect to machine 127.0.0.1: NT_STATUS_LOGON_FAILURE
Failed to change password for <username>

The <username> is a valid Linux account on the machine -- I can log onto a Linux session with it no problem.
The localhost is properly identified in the hosts file.
Iptables is wide open, so the firewall isn't blocking access to the local machine.

I successfully set up Samba on a Debian machine about six months ago and had no problems whatsoever, so I am a bit stumped.

Thanks.

Sounds to me like you missed something like:

Code:

# smbpassword -am client_machine_name

Ah, no. Turns out I forgot to add the user name as a Samba user. Found the answer on page 38 of the Debian Reference. RTFM, you know.

Code:

smbpasswd -a <username>

I had thought Samba picked up the Linux accounts on the machine. I had forgotten that you have to explicitly add them to Samba.

Thanks.

at work, we get the same error described above:

Code:

$ smbpasswd
/* I type in the old and new password */
Could not connect to machine 127.0.0.1: NT_STATUS_LOGON_FAILURE

as well as the following error if I use an alternate command:

Code:

$ passwd
passwd: User not known to the underlying authentication module
passwd: password unchanged

I've been looking at other forums which say these mean the user doesn't exist, but I am attempting to change the password of the user which is currently logged in. we need to know why.
thanks!

This works because you are re-adding the user using the super-user account.

But users would not be able to do this on their own. I still don't know how users can change their own samba password.
