MVC4 Forms Authentication against AD

I am trying to setup an intranet MVC app that authenticates against our company's AD with forms authentication; we do want the user to have to login. I am getting the following exception when posting to the Login action: "To call this method, the "Membership.Provider" property must be an instance of "ExtendedMembershipProvider"." Anyone else had this problem?

Web.config:

<connectionStrings>
  <add name="ADConnectionString" connectionString="LDAP://example.domain.com/DC=example,DC=domain,DC=com"/>
</connectionStrings>
<appSettings>
  <add key="enableSimpleMembership" value="false" />
</appSettings>
<system.web>
<authentication mode="Forms">
  <forms name=".ADAuthCookie" loginUrl="~/Account/Login" timeout="45" slidingExpiration="false" protection="All"/>
</authentication>
<membership defaultProvider="ADMembershipProvider">
  <providers>
    <clear/>
    <add name="ADMembershipProvider" type="System.Web.Security.ActiveDirectoryMembershipProvider" connectionStringName="ADConnectionString" attributeMapUsername="sAMAccountName"/>
  </providers>
</membership>

AccountController:

    [HttpPost]
    [AllowAnonymous]
    [ValidateAntiForgeryToken]
    public ActionResult Login(LoginModel model, string returnUrl)
    {
        //The call to WebSecurity.Login is what throws
        if (ModelState.IsValid && WebSecurity.Login(model.UserName, model.Password, persistCookie: model.RememberMe))
        {
            return RedirectToLocal(returnUrl);
        }

        // If we got this far, something failed, redisplay form
        ModelState.AddModelError("", "The user name or password provided is incorrect.");
        return View(model);
    }

My login was working. It was my logout that wasn't working. In any case, I changed WebSecurity.Logout() to FormsAuthentication.SignOut() and that worked.

Created an MVC3 site in VS2010 and got it working with the ActiveDirectoryMembershipProvider. Then changed the MVC4 AccountController to use the old System.Web.Security instead of WebMatrix.WebData.WebSecurity.

from:

[HttpPost]
[AllowAnonymous]
[ValidateAntiForgeryToken]
public ActionResult Login(LoginModel model, string returnUrl)
{
    if (ModelState.IsValid && WebSecurity.Login(model.UserName, model.Password, persistCookie: model.RememberMe))
    {
        return RedirectToLocal(returnUrl);
    }

    // If we got this far, something failed, redisplay form
    ModelState.AddModelError("", "The user name or password provided is incorrect.");
    return View(model);
}

to:

    [HttpPost]
    [AllowAnonymous]
    [ValidateAntiForgeryToken]
    public ActionResult Login(LoginModel model, string returnUrl)
    {

        if (ModelState.IsValid && Membership.ValidateUser(model.UserName, model.Password))
        {
            FormsAuthentication.SetAuthCookie(model.UserName, model.RememberMe);
            return RedirectToLocal(returnUrl);
        }
        // If we got this far, something failed, redisplay form
        ModelState.AddModelError("", "The user name or password provided is incorrect.");
        return View(model);
    }
