Disconnecting a user from SDL MultiTerm Server interrupts user activity. All unsaved changes are lost. If you want to stop a user from gaining access to the database, remove the user's access to the termbase.
You may want to disconnect users before performing termbase maintenance operations like Stopping the Termbase, or if you want to release CALs.
To disconnect a user:
Right-click on Termbases in the navigation pane and select Disconnect Users....
Select the user and click Disconnect.
Click OK.
