in reply to Form authentication for .NET sites

The form you are trying to use probably uses JavaScript to fill in some fields when you press the submit button. Try using your browser's development tools to see what else is being sent to the server.

With ASP.NET, I know that there is a __doPostBack function that is sometimes called prior to submitting the form, or even WebForm_DoPostBackWithOptions. The latter one usually means that the form is being sent to someplace other than the current page. If you designed this application yourself, you probably want to look at the ASP.NET manuals.

    Hi Thomas, thank you so much for your answers.

    Yes, I can confirm that the site uses JavaScript. The login site is not ours, but we must go through that for us to be able to go through our site. Below is a code snippet of the HTML form. 
    <div id="loginArea">        
        <div id="loginMessage" class="groupMargin">Sign in with your a
+ccount</div>
        <form method="post" id="Login" autocomplete="off" novalidate="
+novalidate" onkeypress="if (event &amp;&amp; event.keyCode
== 13) Login.submitLoginRequest();" action="">
            <div id="formsAuthenticationArea">
                <div id="userNameArea">
                    <input id="userNameInput" name="UserName" type="em
+ail" value="" tabindex="1" class="text fullWidth" spellcheck="false" 
+placeholder="Username" autocomplete="off">     
                </div>
                <div id="passwordArea">
                     <input id="passwordInput" name="Password" type="p
+assword" tabindex="2" class="text fullWidth" placeholder="Password" a
+utocomplete="off">                            

                </div>
                <div id="kmsiArea" style="display:none">
                    <input type="checkbox" name="Kmsi" id="kmsiInput" 
+value="true" tabindex="3">
                    <label for="kmsiInput">Keep me signed in</label>
                </div>
                <div id="submissionArea" class="submitMargin">
                    <span id="submitButton" class="submit" tabindex="4
+" onkeypress="if (event &amp;&amp; event.keyCode == 32) Login.submitL
+oginRequest();" onclick="return Login.submitLoginRequest();">Sign in<
+/span>
                </div>
            </div>
        </form>
    </div>

    Any suggestions or advice on how to go about the form?

    Thanks, Charli

      There could be other JavaScript doing things with the form that isn't visible in your snippet. Again, try to use the development tools (try Ctrl-Shift-K, Ctrl-Shift-I, or right-click and select "Inspect Element") to see what else is sent to the server.
      You should be able to figure it out pretty easily, otherwise the manuals are never far away.
