How to disable “Authentication Required” pop up?

Question

I created a Web Application Using ASP.NET MVC 4, and uploaded it on a commercial web server. My problem is when I click the Actionlink pointing to ~/Account/LogOn, an "Authentication Required" pop up appears.

This is the beginning of my problem because I don't know what settings I changed or is there a setting that I was not able to setup ?

I have created 2 Web Applications before Using ASP.NET MVC 3 and uploaded it on the same commercial web server and it runs perfectly. no hitches what-so-ever.

By the way, the access they gave me to the server is not Remote Desktop Connection, its Parallels.

vipul.surana I was not able to post a picture since I have less than 10 points. So, if it is ok with you I will give you the website address. The website address is www.clktb.com then press login found on the upper right part.

nwdev as per request here is my web.config code I did not change anything here except removing connection string and removed some comments from the original webconfig

Answer 1

Your authentication mode is set to Forms. Do not change it to Windows unless necessary (Windows is only used in a LAN based environment where users are maintained by an Active Directory).

I would check the directory permissions on your web site folder. Go to your website folder & right click Properties->Security & check if Authenticated users are added to the users group.

Also, are you using a webservice?

Edit This is most likely a permissions issue on your website folder. Check this link for more info on IIS http://support.microsoft.com/?id=258063 and also this thread on ServerFault

Answer 2

This here is the removed code of my Account/LogOn.

Based on the words of Mr. Damien Joe I Quote "If the later, then there is definitely an issue with your current website project." I double checked the codes in the VIEW of LogOn since it is premade by ASP.NET MVC 4 and I found a piece of code that is not in MVC 3 LogOn

    <%--<p><%: Html.ActionLink("Register", "Register") %> if you don't have an account. </p>
    <hr />
    <section class="social" id="socialLoginForm">
        <h2>Use another service to log in.</h2>
        <%: Html.Action("ExternalLoginsList", new { ReturnUrl = ViewBag.ReturnUrl }) %>
    </section>--%>

When I removed this piece of code from my View Everything worked perfectly. As in Perfectly. I lost 1 day with this piece of code right here. hopefully, in the future people will see this and know what to do.
