title: Single sign on in ASP.NET - cookie name, machineKey and what more?
body: <p>I have two ASP.NET apps hosted on one server. Their configs have the same machineKey values and the authentication sections look as follows:</p>
  
  <pre><code>&lt;authentication mode="Forms"&gt;
        &lt;forms loginUrl="/_login/default.aspx" name=".MySingleAuth" /&gt;
      &lt;/authentication&gt;
  
  &lt;authentication mode="Forms"&gt;
        &lt;forms loginUrl="~/MySingle/LogOn/0" timeout="2880" name=".MySingleAuth"/&gt;
      &lt;/authentication&gt;
  </code></pre>
  
  <p>The single sign on (authentication in both applications using one cookie) still doesn't work. What am I missing?</p>
  
  <p>Edit: The two apps are on our intranet, one under <a href="https://ip:84">https://ip:84</a> and the other under <a href="https://ip:86">https://ip:86</a> (where ip is an IP).</p>
