Users by default are newly created in the WINDOWS local operating system or domain - these users are then added to the system and assigned access passes. The users are either brought into the system using the Local UDC (User Directory Connector) - or if users attempt ti access the HUB url - and attempts to login - but gets a message that the user does not have an access pass. that user will then appear in the users list in the QMC. You can then assign them the appropriate access pass.
