When using "Require Authentication before retrieving connector configurations" combined with Kerberos, an error may occassionally appear :
Error: A connector configuration has not been assigned to you
Invalid Procedure call or argument (H5) ProvisionITClient:frmAppPortal:tmrDIAppLaunch_Timer
There are several options to choose from.
1. Turn of the Authentication requirement
2. Assign the Configuration based on some other value, such as Computer Name.
3. Use Cached Credentials instead of Kerberos.
Waiting for fix in a future release of vWorkspace
