Finally, next is the login script 

debug ("***********************************************************************");
debug ("****************** LOGIN ON DRUPAL *************************");
debug ("***********************************************************************");
debug (document.url);
user = document.getElementById("edit-name");
pass = document.getElementById("edit-pass");
debug ("***********************************************************************");
if (user != undefined && pass != undefined)
{
    account = secretStore.getAccount("ldap");
    found = false; // Any error message found
    if (account != undefined)
    {
         user.setAttribute("value", account);
    } else {
         user.setAttribute("value", "AUTO-LOGIN");
         found = true;
    }
    user.setAttribute("readonly", true);
    pass.parentNode.setAttribute("style", "display:none");
    errors = document.getElementsByTagName("div");
    for (i = 0 ; ! found && i < errors.length; i++)
    {
        if (errors.item(i).getAttribute("class") == "messages error")
        found = true;
    }
    if (! found)
    {
        body=document.getElementsByTagName("body").item(0);
        div = body.addChild("div");
        div.setAttribute("style", "width: 90%; height: 90%; position: absolute; top: 5%; left: 5%; z-index: +10; background-color: #7F9FC2; color: white; opacity: 0.9; display: table-cell; text-align: center; vertical-align: middle; line-height: 90px; font-size: 250%; ");
        div2 = div.addChild("div");
        div2.setAttribute("style", "width: 100%; height: 40%;");
        div.addChild("span").setText ("Logging in. Please wait ....");
        body.setAttribute("onLoad", "document.getElementById('edit-submit').click();");
    }
    document.getElementById("edit-submit").setAttribute("style", "display:none");
}
// Change login / logout button
anchors = document.getElementsByTagName("a");
for (i = 0 ; i < anchors.length; i++)
{
    if (anchors.item(i).getAttribute("href") == "/?q=user/logout")
        anchors.item(i).setAttribute("href", "/Shibboleth.sso/Logout?return=http://www.soffid.org/");
    if (anchors.item(i).getAttribute("href") == "http://drupal.soffid.org/user")

        anchors.item(i).setText("Login / Register");
    }
    // Remove link to change user attributes
    if (anchors.item(i).getAttribute("href") == "/?q=user/59/edit")
        anchors.item(i).setAttribute("href", "/");
