Sorry if this has been raised already.... We are presently running an NT4-style Samba 3 domain with FDS back end. Good. I was looking at the README for the most recent Samba 4 Technology Preview. There's a section in there that says: "The Samba 4 architecture is based around an LDAP-like database that can use a range of modular backends. One of the backends supports standards compliant LDAP servers (including OpenLDAP), and we are working on modules to map between AD-like behaviours and this back-end. We are aiming for Samba 4 to be powerful front-end to large directories." The fact that FDS isn't mentioned doesn't necessarily mean anything to me, but I wonder if Richard or anyone involved in core FDS development could offer any observations on Samba 4 and the potential for use of FDS as a Samba 4 back end. I will say that making Samba 3 run with FDS back end involved a fair amount of knitting (tho' the same could be said for making Samba 3 run with OpenLDAP back end). I have only gotten so far as to untar the latest Samba 4 TP. Has anyone on list gone so far as to configure Samba 4 with FDS? Thanks, Jim
