ENFORCE_SINGLE_SESSION_PER_USER    
Provides the ability to regulate whether you can maintain only one active session simultaneously. Toggle the flag to "true" manually to enable this setting and enforce a single session constraint.

Default value: False

Note:

Every login session from a different browser is considered as a new session. If the feature is enabled, each session is identified as a concurrent session by the Portal.
