I went to another great Canberra Linux Users Group meeting last night. Alex Satrapa did a demonstration of setting up Samba with OpenLDAP, OpenSSL, etc.
Of course, doing a Samba demo in front of Andrew Tridgell (who is a fairly regular attendee, and a KDE user) resulted in a few comments, and a short cameo when Tridge explained what is happening with Samba 4. Basically there is going to be a single deaemon, listening on about 10-15 ports. In addition to supporting some of the multiple streams required for the fileserver side, it will have the ability to act as an Active Directory server, and SWAT will be built in (perhaps on the grounds that every server design eventually evolves to include HTTP :-) ). After watching a 2.5 hours setup by someone who'd done it twice before that day, clearly it needs to be easier, and the integrated daemon should help that.
