samba - Aug 2005 - Problems with smbldap-tools, passdb backend, smb.conf

Hello,

my passdb backend in the smb.conf m does make troubles.
The entry is: passdb backend=ldapsam:ldap://127.0.0.1.
I seems to be right?
My system is:
Suse 9.2 with openldap 2.2.25-5.2 and samba 3.0.7-5.1
Suse 9.2 clients and Win xp Clients.
If I take the passdb backend entry out of the smb.conf, loggons of the xp 
clients are working for me. If the entry is inside, loggons failed. The Suse 
Clients can login without a problem. The login over smbpasswd seems to work, 
logins over database not.
With smbldap-tools I can create a ldapuser. The smbldap-xxx commands are all 
working for me. But if i want to use smbldap-tools in the smb.conf, like 
"add user script=/usr/sbin/smbldap-useradd.pl -m %u", I need passdb
backend
and the ldap database. The path of the sldap.conf for database is right. And 
database is " database bdb.
Of course the automatic creation of a smb useraccount over the entry of 
smb.conf(/usr/sbin/smldap-useradd.pl -m %u ) at logging in of the xp clients
doesn't work gor me.
Here is an extract of an failed newloggin usercreation(using: 
/usr/sbin/smldap-useradd.pl -m %u in smb.conf). The user testuser was 
created with: "smbldap-useradd testuser":

Sometimes there are logs with the message: bdb permission denied.


Hoping for help and best regards
