I tried to write my own login module for our platform. And I copied the code of DNN AuthenticationService from the DNN source project. But it didn't work.

Any one can give me some advice? following code is what I wrote:

private void LoginUser(string username, string password)

{

var status = UserLoginStatus.LOGIN_FAILURE;

var objUser = UserController.ValidateUser(PortalId, username, password,

"DNN", PortalSettings.PortalName, UserRequestIPAddressController.Instance.GetUserRequestIPAddress(new HttpRequestWrapper(Request)), ref status);

var authenticated = Null.NullBoolean;

var message = Null.NullString;

if (status == UserLoginStatus.LOGIN_USERNOTAPPROVED)

{

message = "UserNotAuthorized";

}

else

{

authenticated = status != UserLoginStatus.LOGIN_FAILURE;

}

// Raise UserAuthenticated Event

var eventArgs = new UserAuthenticatedEventArgs(objUser, username, status, "DNN")

{

Authenticated = authenticated,

Message = message,

RememberMe = false,

};

this.OnUserAuthenticated(eventArgs);

}
