This example uses the steps that are described in the Retrieve a SAML Token procedure.

my $sso_connection = new SSOConnection( 'sso_url' => $my_sso_url );
$sso_connection->login( 'user_name'   => $my_sso_username,
                        'password'    => $my_sso_password,
                        'public_key'  => $my_cert,
                        'private_key' => $my_private_key );
$my_saml_token = $sso_connection->get_token();
