the ldap connection works fine, I've posted some ldap log lines and there is no problem there. I still believe the problem is in the idmap phase.

> Have you installed the libnss-ldap module on Server B? It's required if

> What do you see if you type the command on Server B:
> id <username>
> For example, I have a user in my LDAP database, named "kissg_02a". In my
> case, I see the followings:
> root at lemontree# id kissg_02a
> uid=10003(kissg_02a) gid=513(Domain Users) groups=513(Domain Users)
> Try to set "loglevel 256" on your slapd.conf and look for entries in
> your syslog file, which have an "err" value, other than zero. If you
> don't have any, it means that communication with the LDAP-server works
> as expected, but Samba cannot access the uid attribute. It can also be,
> that the samba.schema file changed since Samba version 3.0, and the new
> version stores UIDs in a different attribute or in a different place of
> the LDAP directory structure. Check if there is a new version available
> for Samba 3.2.
