    when CLIENTSSL_CLIENTCERT {
    set s_dn [X509::subject [SSL::cert 0]]
    set s_serial [X509::serial_number [SSL::cert 0]]
    log local0. "Client Certificate Received: $s_dn"
    if { $s_dn != "" }{
        if { ([matchclass $s_serial contains DatagroupS]) } {
            #Accept the client cert
            log local0. "Client Certificate Accepted: $s_serial"
        } else {
            reject
            log local0. "Failed Cert Auth - No Certificate"
        }
    } else {
        reject
    }
}

     

    Try this, it should work 🙂
