How to Display Windows Username in a PDF File?

Question

I have a PDF form, it has a Name and a Date field, I setup the Date to display todays Date automatically using JavaScript. Now since my users have unique Windows login names. I want to automatically display there username or Windows name in the Name field. Can I do this using JavaScript? or is there a different way? Any help would be greatly appreciated.

Here's a barebones script that you can call from a script in your form to retrieve the login name of the user:
// Folder-level JavaScript function
var getLoginName = app.trustedFunction(
    function () {
        // Get and return the user's login name
        app.beginPriv();
        return identity.loginName;
        app.EndPriv();
This needs to be included in a JavaScript file that's installed in the correct location. It's just a text file, so you can create/edit it with a text editor, but make sure the extension is ".js". For more information about how to determine where to place the file, see: http://acrobatusers.com/tutorials/2006/folder_level_scripts
More information on all of this is in the Acrobat JavaScript reference: http://www.adobe.com/devnet/acrobat/javascript.html
To populate a text field with the login name, do something like:
// Populate field with loginName
getField("text1").value = getLoginName();
Change "text1" with the actual name of the field in your form. You can place this code in a document-level JavaScript so it executes when the form is opened.
Note that all of this code is the bare minimum, and you may want to expand it to check for errors, etc.
