SharePoint onprem library sync to OneDrive authentication problem

Copper Contributor

Hello the SharePoint community,


I've came up with an ask for help regarding the subject.

My goal is to sync the SharePoint onprem library using the OneDrive.

I've got a test farm with a SharePoint Subscription Edition configured, 2 web apps (one is for the mysites). Both web apps are using the Trusted Identity provider.  I did the following configuration

Configure syncing with the new OneDrive sync app - SharePoint Server | Microsoft Learn


During the tests once I click on Sync button in the SP library the OneDrive application starts and after I confirm my email address after a while there another authentication windows pop-ups and it's kind a Windows authentication.

I found also this thread - Setting up Onedrive with Sharepoint 2019 on-premise - getting "There was a problem connecting to One... - where mentioned that only the only NTLM-based authentication supported by the OneDrive application. Unfortunately I found no proof of this anywhere on the OneDrive tech articles.


Is there any way to make it work with the Trusted Identity provider configured on the environment?

Are there any work arounds to make the sync working?
