Many people talk about how Microsoft need to make their products more interoperable through using Open Standards and publishing their own protocols and standards. It was announced in December that Microsoft have licensed a large proportion of their protocol documentation to the SAMBA team, which effectively means in the coming years we will be able to interface with and replace annoying vendor lock-in traps like Sharepoint and Exchange. This is excellent news, and although my blogpost is a little late, I wanted to extend a huge thanks and congratulations to Andrew Tridgell and the SAMBA team on this excellent outcome!
All the details with links and such are on the SAMBA website here. If you are involved in a FOSS project that could benefit from this, you should chat to the SAMBA team.
