I have configured a profile in Connector using the Scan action. We tested it with one user and everything worked correctly, meaning that it opened the scanning interface and passed the token information into the scanning interface.
We tested with a second user and after you click on the Connector icon in the application, it gives a 9013 Error. This is before it ever launches the scanning interface.
To troubleshoot we have opened the Laserfiche client and made sure that the user has permissions to scan into the configured folder in the Connector profile and actually scanned into it without any problems. Not sure what else to test. Using Connector 10.3.
