Unified HMI not communicating to PLC with FW3.1

HMI connection to FW3.1 PLC   Since the new FW3.1 PLC has moved to a User/Role based security concept I get the following error when trying to connect a Unified panel to the PLC   The only way to get the connection to work is to turn off the security, but how can I do this in v19?
