Certificate Express Logon

Certificate Express Logon (formerly known as Express Logon Feature or ELF) enables a Z and I Emulator for Windows Telnet 3270 user to securely logon to a host application without sending the User ID and password. One advantage of using this function is that it reduces the time you spend maintaining host user IDs and passwords. It also reduces the number of user IDs and passwords that the users have to remember.

To use Certificate Express Logon, the host session must be configured for SSL and client authentication. This means the client must have a valid client certificate. The SSL connection must be made to one of the supported Telnet 3270 servers.
