Office365 Sharepoint API fails for federated domains

By : MrVanes

I'm currently exploring the (Academic Licensed) Office365 API via oAuth access_tokens and have succeeded in retrieving a simple OneDrive folder list via the SharePoint API using access tokens, as a proof of concept.

But this seems to work only for users that are in the Azure maintenance domain that's NOT SSO enabled to our on-premise ADFS server.

The domain that is SSO enabled to our own ADFS server succesfully gets logged in on acquiring the oAuth code and I get a genuine access_token while trading in this code. But using this access_token to retrieve a simple folder list for the user results in this error instead of a folderlist.

{"error_description":"The server was unable to process the request due to an internal error. For more information about the error, either turn on IncludeExceptionDetailInFaults (either from ServiceBehaviorAttribute or from the configuration behavior) on the server in order to send the exception information back to the client, or turn on tracing as per the Microsoft .NET Framework SDK documentation and inspect the server trace logs."}

Wich I can't check since I'm not in control of the Azure Sharepoint server.

Did anyone succeed in using the Office365 API icw SSO enabled domains/users?

You'll struggle with an ADFS setup. Any code I've written relies on managed accounts only (i.e. those accounts with a UPN ending with Each synchronised user from on-premise will have a matching secondary identifier which you should use instead.
