    [:blueprint:`handle-multiple-login-sessions-from-same-user-in-horizon`]
    This blueprint allows operators to control if multiple simultaneous
    dashboard sessions are allowed or not for a user. A new setting
    ``SIMULTANEOUS_SESSIONS`` controls the behavior. The default behavior
    allows multiple dashboard sessions for a user. The new setting allows
    operators to configure horizon to disallow multiple sessions per user.
    When multiple simultaneous sessions are disabled, the most recent
    authenticated session will be considered as the valid one and
    the previous session will be invalidated.
