Samba News And New Team Blog

Aug 10, 2009, 12:31 (7 Talkback[s])

[ Thanks to Félim Whiteley for this link. ]

"Firstly, we now have a Samba Team member working at Microsoft ! Congratulations to Chris Hertel, who was offered an opportunity to work directly with Microsoft to create a new set of SMB/CIFS protocol documentation. This will be published as part of the MCPP/WSPP set and made freely available from Microsoft's website.

"This is the first Microsoft-sponsored SMB/CIFS documentation to be made available without restrictions since the 1997 IETF draft specifications. The first new document, [MS-CIFS], covers the SMB protocol as implemented in Windows NT. It is almost 500 pages at present, and is just entering the review and markup stage. It should be available in a few months.

"In order to work with Microsoft on this project, Chris had to found a consulting company and hire a few people.

"Volker Lendecke has been re-writing winbind, making it asynchronous. Here are the details:

"In ancient days, winbind was just a single process. Later on came a separate deamon to update a cache, so that the main code paths in winbind would not be blocked by slow domain controllers or the network being slow to enumerate thousands of users. In an environment where winbind has to authenticate thousands of users from all over the world this can become a bit slow. So with 3.0.20, winbind was turned into a multi-process daemon. One asynchronous main daemon that in good Unix tradition is supported by several helper processes. This architecture made winbind asynchronous for all important code paths. In particular Windows clients logging into a Samba server running winbind could not block winbind from replying to other requests."
