Beginning with BlueZone version 5.1, the BlueZone Mainframe Display emulator has support for the IBM express logon feature, known as Certificate Express Logon. The BlueZone express logon feature allows you to configure BlueZone Mainframe Display sessions that automatically connect to an IBM Mainframe without requiring a user ID and password. When this feature is enabled, the Telnet server on the Mainframe uses certificate information from an SSL connection and the application ID supplied by BlueZone to request a user ID and a PassTicket (a temporary password) from the IBM host access control program RACF.
In order to use this feature, an administrator must configure the host, install certificates if necessary on user computers, configure BlueZone connection settings, and create and modify a BlueZone connection script (.bzs).
