AX 2012 R3 – A user cannot sync to a Document Template Library with federated authentication
and no error message displays,but If you are logged into SharePoint site and try attaching the file then,
it works fine.
Setup is completed following the article below:
This a known issue and the logon prompt was remove when you are accessing the SharePoint Online
through federated access.
You need to logon to SharePoint online in a browser in order to generate the cookie cache
and fix the synchronization issue.
If you are not using federated authentication, where users have a direct connection to SharePoint Online,
then Dynamics AX client will get a normal logon prompt, and complete a basic authentication over SSL.
