How do I resolve the unauthorized client error?

Enable the UDOIT inherited developer key to resolve

This is the text of the error message you may see:

"Authentication problem: Access Denied. unauthorized_client

This error means that the Cidi Labs UDOIT inherited key is not turned on and so the LTI does not have the scoping it needs to work properly.  To resolve the error, go to your Account > Developer Keys > Inherited Keys, click on Show All Keys, and then find and enable the Cidi Labs UDOIT inherited key.  If this does not resolve the issue, please contact support@cidilabs.com
