ADFS as proxy to some IDP

cd flag

As far as I know, Exchange does support WS-Federation, but it does not support SAML. At the same time I have IDP that does support SAML, but does not support WS-Federation.

Is it possible to configure ADFS as proxy? For example: Exchange OWA/ECP -> redirect to ADFS using WS-Fed -> and ADFS speaks to IDP using SAML -> user is getting transparently authenticated using IDP?

Thank in advance.

Thank you. I have read a bit about adding Claims Provider Trust. In Windows 2019 that I'm using I do not see option to specify SAML endpoint, like I could see at the screenshots of the previous versions. Even on the official documentation if one goes to step 'Configure URL' on the page below it displays only an option for WS-Federation endpoint ( https://docs.microsoft.com/en-us/windows-server/identity/ad-fs/operations/create-a-claims-provider-trust

Yes, it's possible to mix protocols.

By default, the user would be redirected to the ADFS screen and there would be a button there (Home Realm Discovery) that would take you to the SAML IDP to authenticate.

Depending on your use case, this may help in that regard.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
