The server access file is an encrypted Vision file that contains records that define which users and client systems are permitted to use AcuServer. The access file manager is used to create and maintain that database. The acuserve -access command is used to start the access file manager from the command line. In the AcuServer Control Panel, the Access tab is used to perform access file manager activities (when you start the ACP, the Access tab is active by default).
See The Server Access File for an introduction to the server access file. See Using the Access File Manager for detailed instructions on using the access file manager.
