Does and How SAPGUI Protocol Support for SAP Single Sign On (SSO) (SSO certificate-based logon)

Hi Experts,

Please help to advise if SAPGUI Protocol Support for SAP Single Sign On (SSO) and how to support the SSO certificate-based logon?

When recording a certificate-based SSO connection, it is scripted in the same way as a user/password log on (sapgui_logon function). User has a requirement to test the performance of SAPGUI including SSO for multiple users, is there any workaround available (eg. by manual scripting)?

Here is the script for logon by SSO as user/password format:

lr_start_transaction("logon");

/*Before running script, enter password in place of asterisks in logon function*/
// Need to perform SAP Single Sign On, replacing sapgui_logon() below
// Authentication to Secure Login Server (SPnego)
// Receive X.509 certificate
// Present certificate to SAP application server
   

 sapgui_logon("USERNAME", 
        "*****", 
        "100", 
        "EN", 
        BEGIN_OPTIONAL, 
            "AdditionalInfo=sapgui4010", 
        END_OPTIONAL);

    lr_end_transaction("logon",LR_AUTO);
