- Authentication via AD FS is supported only for apps hosted by FileMaker Server for Linux starting with version 19.1.2.
- The FileMaker Server administrator needs to set additional options in Admin Console to authenticate users via an AD FS identity provider. See “External authentication for Linux” in the Knowledge Base.
The release notes are somewhat poorly worded in this respect, however. You can, in fact, already use AD FS to authenticate your users in your current deployments.
You can use the in-market version of FileMaker Cloud, which has supported AD FS since version 2.18.x. You can find those instructions in the Claris knowledge base.
And you can also use AD FS if you run your own FileMaker Server on-premise or in the cloud, provided that you have at least FileMaker Server 17.
AD FS turns your Active Directory into an OAuth Identity Provider, using the Open ID Connect mechanism, and that is something that FileMaker Server can use.
As always, if you have any questions about this functionality or OAuth in general, post them here. Or find us on community.claris.com.
