Ldap – Sharepoint 2010 and Samba LDAP groups

The setup:

• Windows 2008 SP2

• Sharepoint 2010 Foundation

• Samba 3 "Domain"

I'm trying to use the Samba LDAP users & groups we already have to access to Sharepoint.

I can successfully authenticate using the Samaba accounts (getting the "Error: Access Denied" message as the user has no permissions). So Sharepoint can clearly see and use the existing accounts/groups.

Signed In but Access Denied http://www.medstv.unimelb.edu.au/sf/acc-den.jpg

What I can't do is be authorised as in the grant permissions interface, Sharepoint now fails to match the account (I get an "No Exact match found…").

Permissions – can't find account http://www.medstv.unimelb.edu.au/sf/permisions.jpg

Is there a way of getting the Sharepoint permissions interface to recognise and use our existing Samba LDAP accounts?

I get it – don't use Samaba, use AD. If I had that option I would, but I don't.
