OLN-363 Azure auth fails for organistion guests

Hi @david-loe – we'll need more information in order to debug this, what errors are you seeing on the client and on the server? It's quite likely this is a restriction on Microsoft's side.

Hi @tommoor, thanks for your fast response!
There are no errors thrown, none on client side and none on server side (also LOG_LEVEL=debug did not reveal anything..)

After successfuly logging in at MS, I'm immediately redirected to the MS login page to login again.

With my self build web apps using passportjs (OAuth 2.0) guest login works (the returned profile has than only a displayName, givenName and familyName are null). And I integrated them the same way as outline on azure side. So I don't think it's on MS side as MS also doesn't throw any login errors.

This is how it looks on client side.
I successfully logged in to MS, and than no redirect to outline happens.

Could you check "Preserve log" in the developer tools and then do the end-to-end auth, we should see all the network requests including redirects on Outline's side

[david-loe]

I just realized that my filters were set to XHR only.. so here is the network history again with more response types

And here the logs:

I didn't find any hint in the logs, maybe you have to try this out on your end and debug on your own 🤷‍♂️
