Sharepoint - 401 unauthorized authentication error


We had successfully configured Duet on our system. Tested the same with a working web service.

As per the new requirement we configured duet workflow on our system.

Now when the SP developer, tries to create a new content type from sharepoint designer, we get an authentication 401 error.

No logs are received in SAP or SP for the same.

The existing services are working fine, but we cannot create a new one or edit an old one in sharepoint designer.

Any help would be helpful.

    Is there a valid user mapping for the (SharePoint) account of that user on your SCL system?

    Transaction SM30 --> Table VUSREXTID.

    And if so, does the mapped SAP user has the SAP authorizations to the SAP data in backend that you try to access?

    Best regards, William.

      one other thought: I guess when using SharePoint designer you are no longer prompted to enter username and password anymore and simply get the 401. Is it possible that the user is locked or that you entered a wrong username / password before?

      In this case, can you open the "User Accounts" settings from the Control Panel on the server where you are using SharePoint designer. Click on "Manage your credentials" and remove the WSDL credentials from the "Generic Credentials".

      Then try again from SharePoint designer. Hopefully you will be prompted for a username and password again.
