We have an ADFS 3.0 server (2012 R2) with O365 SSO configured. There are several partners IdPs, also running ADFS 3. For some reason, when logging in to Lync desktop client, our ADFS server is not forwarding the auth request to partner ADFS servers. The ADFS server tries to log the user in locally, which of course fails. The setup works fine with web browser authentication to O365, passive auth.
Since Lync (and Outlook) uses the ws-trust active profile mechanism to authenticate, is there anything we can configure on the o365 side or in our ADFS server that would mimic HRD behavior?
Thank you!
