To log off users on a Portfolio Server:
Open the Server Administration dialog for the server (File > Administer Servers > [select server] > Administer).
From the list of served Catalogs, locate the Catalog with users that you wish to log off, then click the expansion arrow to view a list of active users on the Catalog.
Select the user that you want to log off.
Click “Log Off User.”
That user will be logged off immediately.
Note: To allow users a time frame within which they can log themselves off (by closing their copy of the catalog), use the “Unserve...” command.
