When connecting to a system, an iView must provide a user name and password. The iView queries the PCD for the default alias of the system to which it wants to connect, then retrieves the user name and password mapped for the current user for this alias.

With dynamic system resolution, a resolving service is allowed to select any valid system defined in the PCD, even one without an alias. However, a system without an alias cannot have a user mapping and, therefore, no iView could connect to such a system.
