In ASP.NET MVC 5, what method set the User object?

I have a application that uses multiple controller inheritance. I override the Initialize(RequestContext requestContext) in multiple levels of my inheritance , but each time I override the Initialize method, I call base.Initialize(requestContext);

[Authorize]
public class FirstBaseController: Controller
{
    protected override void Initialize(RequestContext requestContext)
    {
        base.Initialize(requestContext);
        // Set few custom global things
    }

}

public class SecondBaseController: FirstBaseController
{

    protected override void Initialize(RequestContext requestContext)
    {
        base.Initialize(requestContext);
        // At this point, I am expecting that the `User` object is already set by identity
        //check the claims value here.
    }
}

However if I try to access the User object from inside the Initialize method I found it not yet set!

At what point in time does the framework sets the User object? Which method before the action method I can override where the User object will be set already?

I don't want to use action filter here because I want this logic to get executed on every request.

Using JustDecompile to see the references, the User property really navigates up to the RequestContext reference passed into Initialize (which has a reference to HttpContext). So in Initialize, if the requestContext variable passed into the method has a property HttpContext that is null or HttpContext.User reference is null, then the current user is not available in Initialize().

OnActionExecuting is a good place like @Eric said.

This is going to vary somewhat depending on what method you are using for authentication, but you should be safe to access the User in the `OnActionExecuting' method.

You could also implement that as an action filter and apply that filter to each controller (or to just a base-class controller - it will "carry through" to any controllers that inherit from it)
