join samba client to samba domain

[Pieter Grimmerink]

I've recently updated my samba PDC to 2.2, and now I tried to recreate a
machine account for a samba client. I started with a new smbpasswd file,
followed all the instructions, etc.

When I try to create a machine account on the Samba server with

samedit -U root
createuser client$

it tells me to use lsaquery first, to get my SID
This seems to be a function in rpcclient.
This one fails.

When I try to join the domain with

rpcclient -U root
createuser client$ -j

from the client machine, this also fails, telling me to use lsaquery first.

Does anyone know what causes this problem?
How should I proceed?

Best regards,
