Hi,

I have a problem migrating Samba,  users can't be authenticated. It 
always says "user unknown or incorrect password".
I have low skills on Samba so I followed the official HOW-TO install 
step-by-step, but now I'm stucked.

Everything works well on the (old) 3.0.23d Samba server.
I can't add a machine to the workgroup using the admin account 
(administrator).

I migrated the smb.conf file and the persistent *.tdb files.
When I do a "tdbedit -Lv administrateur" (the administrator), I can see 
the details of the user on both servers.

The two servers uses the same backend DB (a MySQL service).
Smbd logs confirms it can connect correctly to the DB.

testparm runs are successfull.

When I try to connect to Samba with "smbclient -U administrateur -L PDC" 
: setup session failed: NT_STATUS_LOGON_FAILURE
As I saw while searching the source problem on the web, root account exists.
I thought this was a problem in the authentication mechanism. So I tried 
using "encrypt passwords = Yes" unsuccessfully.

If anyone can point me a direction, this can be helpfull,
Thanks
