Unrecognized element 'authentication'.
<p>I am trying to write a simple authentication. I'm also trying to make this quick and learn about the forms authentication via web.config.</p>

<p>So i have my authentication working if I hard code my 'user name' and 'password' into C# code and do a simple conditional.</p>

<p>However, I get en error message '<strong>Unrecognized element 'authentication'.</strong></p>

<pre><code>Line 2:     &lt;system.web&gt;
Line 3:         &lt;customErrors mode="off"&gt;
Line 4:             &lt;authentication mode="Forms"&gt;
Line 5:                 &lt;forms name=".C#FEWD" 
Line 6:                     loginUrl="/schools/admin/login/index.aspx" 
</code></pre>

<p>My web.config file looks like this:</p>

<pre><code>&lt;configuration&gt;
    &lt;system.web&gt;
        &lt;customErrors mode="off"&gt;
            &lt;authentication mode="Forms"&gt;
                &lt;forms name=".C#FEWD" 
                    loginUrl="/schools/admin/login/index.aspx" 
                    protection="All" 
                    timeout="60"&gt;
                    &lt;credentials passwordFormat="Clear"&gt;
                        &lt;user name="schools" password="magic" /&gt;
                    &lt;/credentials&gt;
                &lt;/forms&gt;
            &lt;/authentication&gt;
        &lt;authorization&gt;
            &lt;deny users="?" /&gt;
        &lt;/authorization&gt;
        &lt;/customErrors&gt;
    &lt;/system.web&gt;
&lt;/configuration&gt;
</code></pre>
