ASP.NET beginners quetions
<p>I am trying to create my first web application using ASP.NET. I've created new sample ASP.NET project application.</p>

<p>First of all I want to understand how do I switch from local App_Data file to proper database and how whole authentication process is working. </p>

<ol>
<li><p>Db switch. What I did is, attached current example of .mdf file through SQL management studio on a server. But I am not sure how should I modify my connection string. Could you help me please? </p>

<p>connectionString="data source=.\SQLEXPRESS;Integrated Security=SSPI;AttachDBFilename=|DataDirectory|\aspnetdb.mdf;User Instance=true"</p></li>
<li><p>Could you please explain how authentication is working? Say after user enter its credentials and hits enter, somewhere in a code it has to validate username and password, but I can't find where it happens. </p></li>
</ol>

<p>Lets say my user A is Moderator and user B is simple user. How should I detect which one it is? How do I display extra features for user A, since he is a Moderato?</p>
