SharePoint 2010 - JavaScript Web Service - HTTP 401 authentication error

Question

UPDATE

Folks, I just noticed that even if I remove ALL javascript mentioned in original question, I still get same error. All I am using is JQuery and Nivo Slider for slideshow. I think it may a configuration issue.

--- Original Question is below --- 

SharePoint 2010 

This code gives me a lot of HTTP 401 Authentication errors. Any help on how to fix will be appreciated. Thanks in advance.

    function GetAllImages() {
        //$("#slideshowPicturePlaceholder").css("display", "block");
       // Query without where clause soapEnv += "<Query><OrderBy Override='TRUE'><FieldRef Name='Created' Ascending='FALSE' /></OrderBy></Query>";
        var soapEnv = "<soapenv:Envelope xmlns:soapenv='http://schemas.xmlsoap.org/soap/envelope/'><soapenv:Body><GetListItems xmlns='http://schemas.microsoft.com/sharepoint/soap/'><listName>SlideShow</listName><query><Query><Where><Or><IsNull><FieldRef Name='Expires'/></IsNull><Geq><FieldRef Name='Expires'/><Value Type='DateTime'><Today /></Value> </Geq></Or></Where><OrderBy Override='TRUE'><FieldRef Name='Order' Ascending='FALSE' /></OrderBy></Query></query><viewFields><ViewFields><FieldRef Name='Expires'/><FieldRef Name='Title'/><FieldRef Name='ows_FileLeafRef'/><FieldRef Name='URL'/></ViewFields></viewFields><rowLimit></rowLimit></GetListItems></soapenv:Body></soapenv:Envelope>";

        $.ajax({
            url: "/_vti_bin/lists.asmx",
            type: "POST",
            dataType: "xml",
            data: soapEnv,
            complete: processQueryResults,
            contentType: "text/xml; charset=utf-8",
            error: function (xhr) {
                alert('Error!  Status = ' + xhr.status);
            }
        });
    }

    function processQueryResults(xData, status) {

        //Change the below to point to your image library
        var imageURL = "/SlideShow/";
        var itemURL = "/SlideShow/Forms/DispForm.aspx?ID=";

        //Show XML output (Do not use IE)
        //console.log(xData);

        $("#slider").html("")

        // Not Working in Safari and Chrome 
        //$(xData.responseXML).find("z\\:row").each(function () {
       
       // Also working in safari and Chrome
        $(xData.responseXML).find("[nodeName='z:row']").each(function(i) { 

            var title = $(this).attr("ows_Title");
            var imageLink = imageURL + $(this).attr("ows_FileLeafRef").substring($(this).attr("ows_FileLeafRef").indexOf('#') + 1);
            var itemLink = itemURL + $(this).attr("ows_ID");

            //Dubble data in URL (URL%20Description) var linkURL = $(this).attr("ows_URL").split(";#");
            var linkURL = $(this).attr("ows_URL").substring(0, $(this).attr("ows_URL").indexOf(","));

            //Use target='_blank' in order to open new window
            var liHtml = "<a href='" + linkURL + "' target='' border='0'><img border='none'  src='" + imageLink + "'/></a>";

            $("#slider").append(liHtml);
        });
		$("#slider").css("display", "block");
		$('#slider').nivoSlider();
     }
    GetAllImages();

Hi ran009.

Can you see what items gives the 401? Perhaps you can see this in the eventlog on the SharePoint web server or by using fiddler or similar on the VS box.

Answer 3

Hi ran009,

Greetings! Thanks for the post.

Can you please provide more details about the issue? Please respond to the fowlling queries:-

1. Is this an inter-mittent issue or are you always hittting a 401 error?
2. So, does the user, who is trying to access the javascript, have read permissions on this site? (I see that you are getting images from a library using the Lists.asmx and the user would require the necessary permissions)
3. Where you able to see any related errors in the ULS logs?

By providing these information, it would help us in identifying the root cause and thereby leading us to a quicker resolution.

Answer 4

General
- In IE/FF browsers the page loads fine.
- In Chrome the page loads, but continuously asks for login/password. (If we access it via external address like something.com, but it works fine on intranet).
- When I debug with Fiddler, I notice many of my css/js/image files show up with 401 status.

Your answers:

1. As explained above.
2. Yes, permissions are fine. 
3. 401 is visible in Fiddler, but I do not see any occurrence in ULS.

Thanks folks.

Answer 5

When I use Chrome and internet URL for my site (NOT Intranet URL) then:

Using fiddler, I see all of my css/images/js files are being listed with 401. Also all of them get repeated many a time, as long as the Chrome is open. Copy and paste from fiddler is below.

Answer 7

Hi ran.

In summary:

This only accours in FF?
This occurs with or without Java?
The 401 comes from accessing among other things the /Layouts lirary?

I Think that FF as to be configured like IE to authenticate automatically with logged on credentials for a trusted site, else it will keep prompting?

Anyway, since this is only FF and even Chrome works, my thought is that SharePoint probably uis not the bad guy this time...:-)

If you were to try only(not in prod) to set the permissions to internet url to Anonymous, then it would probably work right?

I really hope you find it!

Answer 9

It must be something related to SharePoint configuration on my DEV server, when I move it to UAT it works fine. So as of now I consider this resolved.

Thanks all.
