After upgrading to 3.4.0, I can no longer add new users. Any users

The server is Ubuntu 9.10 running Samba 3.4.0.
I am using:

Updating passwords for existing users using passwd successfully

However, if I do:
smbpasswd -x user
Failed to find entry for user smbuser.
If I add a new user using:
useradd newuser
passwd newuser
smbpasswd -a newuser
This appears in auth.log:

And if I attempt to authenticate (samba.log):

Now... Here's where it gets interesting. At this point, I converted
my smbpasswd containing newuser to tdb...:
pdbedit -i smbpasswd -e tdbsam
...the account newuser now authenticate over SMB. However, adding
any other new users is still not working.
I have attempted to repeat the steps described above for adding a
user and then converting smbpasswd to tdb again, but to no avail.
I have not defined passdb backend in smb.conf.
Anyone know what could be causing this?
Did you check the output of "testparm -v" to make sure the password
backend and password file is where you expect it to be?
Did you try adding a user with "pdbedit" instead?
Can you type "which smbpasswd" "which pdbedit" etc - I suspect you
are using "smbpasswd" command from the "old" version of samba.
Thanks for the reply. You're right, the documentation I had read said
that smbpasswd would work with the new tdb backend. Can I not use it?
For now, here are the outputs you requested:
From testparm:
passdb backend = tdbsam
idmap backend = tdb
idmap alloc backend =
From which:
/usr/bin/pdbedit
/usr/bin/smbpasswd
Maybe this will help, smbuser is a new user on my system who cannot
authenticate over SMB. When I try to use smbpasswd -a -D10 smbuser I
get an error in the middle of the output that says:
Get_Pwnam_internals did find user [smbuser]!
Here is the full output:
[root@server:/]# smbpasswd -a -D10 smbuser

"testparm -v" should verify that samba is also using
"/etc/samba/passdb.tdb" for the password file. You can use "tdbdump"
to view the contents of that file.
Did you create the unix user first? Does that user exist in
/etc/passwd? (assuming you are not using winbind to automatically
create unix uid's in an idmap tbd file.) Does "getent passwd" show the
unix user?
