21 | /** | |
22 | * Thrown when an authentication attempt has been received for an account that has already been | |
23 | * authenticated (i.e. logged-in), and the system is configured to prevent such concurrent access. | |
24 | * | |
25 | * <p>This is useful when an application must ensure that only one person is logged-in to a single | |
26 | * account at any given time. | |
27 | * | |
28 | * <p>Sometimes account names and passwords are lazily given away | |
29 | * to many people for easy access to a system. Such behavior is undesirable in systems where | |
30 | * users are accountable for their actions, such as in government applications, or when licensing | |
31 | * agreements must be maintained, such as those which only allow 1 user per paid license. | |
32 | * | |
33 | * <p>By disallowing concurrent access, such systems can ensure that each authenticated session | |
34 | * corresponds to one and only one user at any given time. | |
