Hi Everyone,

Using Fedora8.

I find some users I create have no problem having their smb
passwords changed using smbpasswd. Others simply don't work and I
get the error message "Failed to modify password entry for user
<whatever>".

What are the possible causes for this, and could you point me at a
method of fixing it please?

I remember from a fiddle I had with Linux some years ago that I
used to have to copy the OS user passwords to SMB passwords using
a method like this...

cat /etc/passwd | mksmbpasswd.sh > /etc/samba/smbpasswd

Is this procedure still required?

---- No way...and I don't recall when that ever would have worked.

users changing their password from command line smbpasswd, I've
never seen that fail. It makes no sense that it would fail.

Hi Craig,

Thanks for the help.

So I should never need to do this?

Okay, so how does Samba authenticate users (no other server) is it
with the smbpasswd file? If so how does it get its info?

In stupidity and desperation I've managed to break my smbpasswd file.
Now the command smbpasswd -a <name> doesn't function at all. Is there
anyway to repair it? Or get a default copy?

---- not that I am aware of...backup is the method used to protect
yourself ----

Bugger!

The amazing thing is, the samba shares still work after a reboot with
no smbpasswd file. I'm so confused, I think i've got my head around
how it works and then something comes along and proves I had it wrong
again.

I only want to set up samba shares. <sob>
---- I'm not sure that Fedora 9 uses an smbpasswd passdb by default.

I think I'm using Fedora 8. Well, making a dog's breakfast of more like.

What is output (as root) of command... testparm -s |grep passdb

[root@DarkStar ~]# testparm -s |grep passdb

passdb backend = tdbsam
----
that last line, 'passdb backend = tdbsam' means that you aren't using
smbpasswd for your data store for users which is a good thing since
tdbsam is more substantial than a flat file. Users / passwords are
stored in /var/lib/samba/private/passdb.tdb|secrets.tdb

You might want to up the debugging level to find out if/why it's failing
then try that.
