ASP.NET MVC 3 AuthorizeAttribute - asp.net

Question

I am developing a project using ASP.NET MVC 3, now use a MembershipProvider, RoleProvider AuthorizeAttribute and custom. So in certain parts of the code use this:
[Logon(Roles = "login, test1")]
This code works perfectly, for use in the MembershipProvider code:
public override string [] GetRolesForUser (string username)
{
var = UsuarioRepository.GetListaPermissoesByUsuarioEmail permissions (username);
if (permissions == null)
{
nullPermissao var = new string [0];
nullPermissao return;
}
return permissions;
}
My question is. how can I use the following code, which method will need to customize?
I want to check is determined whether a particular type of user who is logged in and if it has certain privileges.
[Logon(Roles = "login, test1," Users = "User1")]
Using override string [] GetRolesForUser (string username) method it checks the Roles, in wich method I can check the User?

Answer 1

This should work out of the box with the AuthorizeAttribute. It checks if HttpContext.User.Identity.Name matches any of the terms you defined under AuthorizeAttribute.Users
As i see from the comments, you rolled your own LogonAttribute where your probably overwrote the OnAuthorize method. This is where the AuthorizeAtrribute does it`s magic.
Original ASP.NET MVC Source
protected virtual bool AuthorizeCore(HttpContextBase httpContext)
{
if (httpContext == null)
throw new ArgumentNullException("httpContext");
IPrincipal user = httpContext.User;
return user.Identity.IsAuthenticated && (this._usersSplit.Length <= 0 || Enumerable.Contains<string>((IEnumerable<string>) this._usersSplit, user.Identity.Name, (IEqualityComparer<string>) StringComparer.OrdinalIgnoreCase)) && (this._rolesSplit.Length <= 0 || Enumerable.Any<string>((IEnumerable<string>) this._rolesSplit, new Func<string, bool>(user.IsInRole)));
}
public virtual void OnAuthorization(AuthorizationContext filterContext)
{
if (filterContext == null)
throw new ArgumentNullException("filterContext");
if (OutputCacheAttribute.IsChildActionCacheActive((ControllerContext) filterContext))
throw new InvalidOperationException(MvcResources.AuthorizeAttribute_CannotUseWithinChildActionCache);
if (this.AuthorizeCore(filterContext.HttpContext))
{
HttpCachePolicyBase cache = filterContext.HttpContext.Response.Cache;
cache.SetProxyMaxAge(new TimeSpan(0L));
cache.AddValidationCallback(new HttpCacheValidateHandler(this.CacheValidateHandler), (object) null);
}
else
this.HandleUnauthorizedRequest(filterContext);
}

Did you mean to use the following?
[Authorize(Roles = "login, test1", Users = "User1")]
