I have a setup made-up of 2 machines:
- one Windows Server 2012 with Sharepoint 2016 (and other additional features like DNS, ADFS, ADDS, ADCS, etc.)
- one "client machine" used to access the Sharepoint, also with Office 2016 installed.
The Sharepoint is configured to use an ADFS Trusted Identity provider, and Windows Authentication is disabled. Logging-in to Sharepoint with users from that domain works fine. (eg. [email protected])
THE PROBLEM: I click an Office document in Sharepoint (eg. sample.docx), I use the "Open in Word" feature, the Word app opens and prompts for SharePoint credentials in order to open the file. The same credentials that I use to browse the SharePoint form a browser, do not work in Word. (same problemf or excel, powerpoint, etc...) I tried various syntax forms (usernam[email protected], DOMAIN.NAME\username), but it made no difference.
Any ideas to fix this ?
