From dmulder at samba.org Wed Aug 12 20:13:14 2026 From: dmulder at samba.org (David Mulder) Date: Wed, 12 Aug 2026 14:13:14 -0600 Subject: [cifs-protocol] Renewed Request for Entra ID Interoperability Documentation Message-ID: I previously requested documentation necessary to implement interoperable Entra ID authentication, device identity functionality, and Intune compliance on Linux and was told that Microsoft's interoperability documentation obligations did not extend to Microsoft's cloud protocols. Since that exchange, the European Commission has opened a DMA market investigation specifically concerning Microsoft Azure, has preliminarily concluded that Azure should be designated a gatekeeper, and is conducting a parallel Article 19 investigation examining cloud interoperability barriers and whether existing DMA interoperability obligations should be extended to cloud computing services. In light of these developments, I would like Microsoft to reconsider its previous position and work with Samba and Himmelblau to validate and complete the protocol documentation necessary to achieve effective interoperability with Microsoft's Entra ID services. As with my previous requests, I am supplying the interoperability documentation I have already developed through implementation and protocol analysis. What we need most is Microsoft's assistance validating and correcting the existing documentation and filling in the portions that cannot reasonably or reliably be determined through network analysis alone. I will also be attending Microsoft's IOLab at SNIA SDC next month and would welcome the opportunity to discuss this work there with the protocol teams. Given the European Commission's renewed focus on cloud interoperability, I believe this is a good opportunity for Microsoft, Samba, and Himmelblau to resolve this issue constructively. -- David Mulder Labs Software Engineer, Samba SUSE 1221 S Valley Grove Way, Suite 500 Pleasant Grove, UT 84062 (P)+1 385.208.2989 dmulder at suse.com http://www.suse.com -------------- next part -------------- A non-text attachment was scrubbed...
