    text
    copied!<p>In an ASP.net application I'm using a Login control with a custom membership provider that I wrote. What I want to do is to set <code>Thread.CurrentPrincipal</code> to my custom Principal object, just after the user is authenticated.</p> <p>I'm using the setter: <code>Thread.CurrentPrincipal</code> and it sets the Principal object for me but, on all the consequent threads this CurrentPrincipal is overridden with the default one.</p> <p>Here is my code for the Authenticate event of the Login control:</p> <pre><code>protected void Login1_Authenticate(object sender, AuthenticateEventArgs e) { string username = Login1.UserName; string password = Login1.Password; if (Membership.ValidateUser(username, password)) { var login = sender as Login; var phoenixIdentity = new PhoenixIdentity("B", "Forms" , true); var principal = new PhoenixPrincipal(phoenixIdentity); Thread.CurrentPrincipal = principal; AppDomain.CurrentDomain.SetThreadPrincipal(principal); HttpContext.Current.User = principal; e.Authenticated = true; } } </code></pre> <p>For example, imagine that I login with the username A, everything goes well... Validation passes, but I hardcode the user with the username B in the Identity object which is set to the Principal object I set as the <code>CurrentPrincipal</code> object.</p> <p>When I check which user is set to the <code>CurrentPrincipal</code> Identity at the end of this method it says it's user B. But when I load another page and then check what the Identity of the <code>CurrentPrincipal</code> is, it says it's user A.</p> <p>So, how can I make my <code>CurrentPrincipal</code> object to be persistent across all other threads, and where/when does this Login control set the <code>CurrentPrincipal</code> object of the Thread?</p>
