I create my own IPrincipal
and IIdentity
implementation as shown below:
[ComVisible(true)]
[Serializable]
public sealed class CustomIdentity : IIdentity {
private readonly string _name;
private readonly string _email;
// and other stuffs
public CustomIdentity(string name) {
_name = name.Trim();
if(string.IsNullOrWhiteSpace(name))
return;
_email = (connect to database and read email and other stuffs);
}
public string Name {
get { return _name; }
}
public string Email {
get { return _email; }
}
public string AuthenticationType {
get { return "CustomIdentity"; }
}
public bool IsAuthenticated {
get { return !string.IsNullOrWhiteSpace(_name); }
}
}
[ComVisible(true)]
[Serializable]
public sealed class CustomPrincipal : IPrincipal {
private readonly CustomIdentity _identity;
public CustomPrincipal(CustomIdentity identity) {
_identity = identity;
}
public bool IsInRole(string role) {
return _identity != null &&
_identity.IsAuthenticated &&
!string.IsNullOrWhiteSpace(role) &&
Roles.IsUserInRole(_identity.Name, role);
}
IIdentity IPrincipal.Identity {
get { return _identity; }
}
public CustomIdentity Identity {
get { return _identity; }
}
}
Also, I create a HttpModule
and in its AuthenticateRequest
event, I do this:
public void Init(HttpApplication context) {
_application = context;
_application.AuthenticateRequest += ApplicationAuthenticateRequest;
}
private void ApplicationAuthenticateRequest(object sender, EventArgs e) {
var formsCookie = _application.Request.Cookies[FormsAuthentication.FormsCookieName];
var identity = formsCookie != null
? new CustomIdentity(FormsAuthentication.Decrypt(formsCookie.Value).Name)
: new CustomIdentity(string.Empty);
var principal = new CustomPrincipal(identity);
_application.Context.User = Thread.CurrentPrincipal = principal;
}
Also, I create my own Controller
and WebViewPage
like these:
public abstract class CustomController : Controller {
public new CustomPrincipal User {
get {
var user = System.Web.HttpContext.Current.User as CustomPrincipal;
return user;
}
}
}
public abstract class CustomWebViewPage<TModel> : WebViewPage<TModel> {
public new CustomPrincipal User {
get {
// (Place number 1) here is the error I'm speaking about!!!
var user = HttpContext.Current.User as CustomPrincipal;
return user;
}
}
}
as shown in above code, it seems everything is right; But as you can see, in Place number 1 I can't access the CustomPrincipal
! Means in this place, I have a RolePrincipal
instead of having a CustomPrincipal
. e.g. HttpContext.Current.User
is a RolePrincipal
instead of CustomPrincipal
. But the RolePrincipal.Identity
property is a CustomIdentity
!
Your mistake is here:
_application.AuthenticateRequest += ApplicationAuthenticateRequest;
There is a HttpModule
named RoleManagerModule
that invokes a method in HttpApplication.PostAuthenticateRequest
and sets the HttpContext.Current.User
to RolePrincipal
. So, you were setting the User
in AuthenticateRequest
and the RoleManagerModule
sets it in PostAuthenticateRequest
, means after your set, so overrides your settings. Change your Module.Init
:
public void Init(HttpApplication context) {
_application = context;
// change just this line:
_application.PostAuthenticateRequest += ApplicationAuthenticateRequest;
}

Please see this question -asked by starter again, depended on current question- for a second solution, if this one doesn't work.
