Rajeev Pentyala – Microsoft Power Platform

We were getting below exception when we click “Track in CRM” button from CRM 2011 outlook client

The user authentication passed to the platform is not valid

User Authentication Invalid

Fix

We fixed the issue by providing the “Act on Behalf of Another User” privilege to the User’s security role

Act on Behalf of Another User

So what is this privilege “Act on Behalf of Another User”?

• This privilege defines whether the user can impersonate another user.
• For example, you might want the system administrator to impersonate another user to act on behalf of the other user when doing some operations.
• Impersonation is only possible using the SDK and plugins, not in the application.

Another scenario

• You would get the same exception when you try to login to CRM with specific users.
• The reason could be your CRM user’s AD account is either deleted or re-created with different domain name.
