To create a
custom membership provider I followed these instructions:
http://stackoverflow.com/questions/2771094/asp-net-mvc2-custom-membership
and these:
http://mattwrock.com/post/2009/10/14/Implementing-custom-Membership-Provider-and-Role-Provider-for-Authinticating-ASPNET-MVC-Applications.aspx
So far, I've managed to implement
custom membership provider and that part works fine. RoleManager still needs some modifications...
Project structure:
SAMembershipProvider.cs:
public class SAMembershipProvider : MembershipProvider
{
#region - Properties -

public bool enablePasswordReset { get; set; }

public bool requiresUniqueEmail { get; set; }
public int maxInvalidPasswordAttempts { get; set; }
public int passwordAttemptWindow { get; set; }
public MembershipPasswordFormat passwordFormat { get; set; }
public int minRequiredNonAlphanumericCharacters { get; set; }

if (!provider.ValidateUser(userName, password))

In some testing controller I have following:
[Authorize]
public class ContactsController : Controller
{
SAMembershipProvider saMembershipProvider = new SAMembershipProvider();
SARoleProvider saRoleProvider = new SARoleProvider();
//
// GET: /Contact/
public ActionResult Index()
{
string[] roleNames = Roles.GetRolesForUser("
[email protected]");
// Outputs admin
ViewData["r1"] = roleNames[0].ToString();
// Outputs True
// I'm not even sure if this method is the same as the one below
ViewData["r2"] = Roles.IsUserInRole("
[email protected]", roleNames[0].ToString());
// Outputs True
ViewData["r3"] = saRoleProvider.IsUserInRole("
[email protected]", "admin");
return View();
}
If I use attribute [Authorize] then everything works ok, but if I use [Authorize(Roles="admin")] then user is always rejected, like he is not in role.
Any idea of what could be wrong here?
Thanks in advance,
Ile
