Answer 1

Short story : You seem to be trying to use MVC filter and MVC binding on a webapi controller. That's why it does not work.

Long story : first create a webapi filter provider ( note, you will need Ninject.Extensions.Factories package to have Func resolved by Ninject)

public class AuthorizeViewFilterProvider : System.Web.Http.Filters.IFilterProvider
{
    private readonly Func _authorizeViewFilterFactory;

    public AuthorizeViewFilterProvider(Func authorizeViewFilterFactory)
    {
        this._authorizeViewFilterFactory = authorizeViewFilterFactory;
    }

    public IEnumerable GetFilters(HttpConfiguration configuration, HttpActionDescriptor actionDescriptor)
    {
        if(!actionDescriptor.GetCustomAttributes().Any())
            return Enumerable.Empty();

        return new[]
        {
            new FilterInfo(this._authorizeViewFilterFactory(), FilterScope.Action)
        };
    }
}

then create a webapi filter

public class AuthorizeViewFilter : System.Web.Http.Filters.IAuthorizationFilter
{
    private readonly IAccessRightsService _iAccessRightService;
    public AuthorizeViewFilter(IAccessRightsService iAccessRightService)
    {
        _iAccessRightService = iAccessRightService;
    }

    public Task ExecuteAuthorizationFilterAsync(
        HttpActionContext actionContext,
        CancellationToken cancellationToken,
        Func> continuation)
    {
        RoleFeature roleFeature = _iAccessRightService.GetRoleFeatures();

        if (roleFeature.IsView)
        {
            return continuation();
        }
        else
          return Task.FromResult(actionContext.Request.CreateErrorResponse(HttpStatusCode.Forbidden, "Access denied"));
    }
}

then, bind the FilterProvider in your binding setup :

this.Bind().To();
