Automating Login Using the Express Logon Feature


Automating Login Using the Express Logon Feature


The Express Logon Feature (ELF) lets a user running a 3270 client session log on to a host system using a digital certificate instead of a user ID and password.

To use the Express Logon Feature, make sure that the following are true:

  • The host session is configured for SSL with client authentication.
  • Each user has a unique digital certificate.
  • The connection is to a supported VT server.

An Express Logon macro sends tags for the username and password. The tags are USR.ID for username and PSS.WD for password. As a result, your username and password are not sent over the connection. In order for an application to be accessed using the Express Logon Feature, a PassTicket data class profile (PTKTDATA) must be defined on the host system.

To automate your login using the Express Logon Feature:

Do one of the following:

  • Create an ELF macro using the macro record function. You can record an ELF macro by performing your normal logon procedure and entering the tags instead of your real username and password.
  • Use the sample logon macro (ExpressLogonTSO.ebs) that is installed in your Macro folder. You may need to change the logon string for the application ID (APPLID) that the host server uses to identify the application. Your host system administrator can provide you with the Application ID.
