Verify that OAuth is configured correctly for the Machine Translation Service application proxy (SharePoint Server)
APPLIES TO: 2013 2016 2019 Subscription Edition SharePoint in Microsoft 365
Rule Name: Verify that OAuth is configured correctly for the Machine Translation Service application proxy.
Summary: The Machine Translation Service application proxy that is provisioned on the farm can function correctly only when OAuth is correctly configured.
Cause: OAuth is not configured correctly for the Machine Translation Service application proxy.
Resolution: Ensure that every Web application with a Machine Translation Service application proxy has a connection to a User Profile service application and an App Management service application, and is in claims-based authentication mode.
Verify that the user account that is performing this procedure is a member of the Farm Administrators group.
On the SharePoint Central Administration website, click Application Management.
On the Application Management page, in the Service Applications section, click Configure service application associations.
In the Application Proxy Group column, click the proxy group for the Web application or service application that you want to configure. Usually it is the default Application Proxy Group.
Select the User Profile Service Application Proxy check box and the App Management Service Application Proxy check box.
Go back to Central Administration and in the Application Management section, click Manage web applications.
Click the Web application you want to configure, and then click the Authentication Providers button on the ribbon.
Ensure that the Membership Provider Name for the Default zone is Claims Based Authentication. If not, you have to migrate the Web applications from classic mode to claims-based authentication. For more information, see Migrate from classic-mode to claims-based authentication in SharePoint Server.
