Forms authentication between applications
<p>I have a ASP.NET application with Forms authentication. I also have a subfolder setup as a separate application (not virtual directory), using the same application pool and using the same web.config authentication settings.</p>

<p>For some reason I don't understand, these two applications do not share the same authentication. For instance, FormsAuthentication.SetAuthCookie seems to work independently, and User.Identity.Name returns different values in the two applications.</p>

<p>My question is, how can they share the same authentication? I want to login into one app, and appear under the same identity on the other. I can see the .ASPAUTH cookie has the same value (obviously, since they are under the same domain). But how would single sign-on work?</p>

<p>Thanks
