I'm setting up a samba domain controller on Feisty serving about 10 Windows XP clients and wondering how best to go about setting up the users/groups i need. At the moment I was just going to create the users and groups in ubuntu and convert them to samba users through webmin. Is this the best way or do i need to use openLDAP? In particular I'm looking at the "passdb backend" line in smb.conf. because i'm not sure what to put in there.
