As with regular logins, you can login to your computer when it does not have a connection to its domain, say, on a remote location.
Offline Login requires SystoLOCK Companion to be involved
To take advantage of this functionality, the capability has to be enabled for every computer that can go offline. By default this capability is not enabled.
You enable this capability by adding the computers in question to a special AD group,
SystoLock Offline Computers. The membership can be either direct or indirect.
Members of this group will register themselves for Offline Login upon start and first Login with SystoLOCK.
