It's always worth catching a talk from Andrew Tridgell. He's very funny, informative, and always makes his topic accessable to the entire audience.
This year's Tridge Talk was on Samba 4, which has just released it's first technology preview. As always, the room was packed -- I really feel for any speaker who's in a parallel session against Tridge, because he's always such a big drawcard, no matter what the topic.
But of course, a talk is always so much more impressive with a demo. The chosen feature was the entertainingly named "Vampire tap" functionality -- "now with longer fangs". You take a Win2k3 domain controller, a Windows XP workstation joined to that domain, and a Samba 4 server. Point the Samba server's fangs at the Win2k3 box, wait a few seconds, shut down the Win2k3 server, change a couple of settings in Samba, restart the Samba service, and then log in again on the Windows XP machine.
It all Just Worked.
I avoid supporting Windows machines wherever possible, but when such an eventuality is unavoidable, it looks like Samba 4 will make the process significantly less painful.
