IPriciple implementaion

[anjummir]

hello,

I was wondering if creating a custom Ipriciple is not going to hurt performance of my application. I was debugging my code and it seems that on every request my principle object is recreated. in other words i am having to access AD on eah request. can someone tell me if this is the right approach?

 void Application_AuthenticateRequest(Object sender, EventArgs e)
    {
       if (Request.IsAuthenticated == true  && this.User != null)
        {
            //Construct SecurityManager with AD path passed in from web config.
            SOLARBusinessLayer.SecurityManager objSec = new SOLARBusinessLayer.SecurityManager();
            objSec.ADPath = ConfigurationManager.ConnectionStrings["ADConnectionString"].ToString();
            objSec.ADUserName = ConfigurationManager.AppSettings["USERNAME"].ToString();
            objSec.ADPassword = ConfigurationManager.AppSettings["PWD"].ToString();     
            //Create a CustomPrincipal for the current user.
            SOLARBusinessLayer.SolarPrincipal cprPrincipal = objSec.ConstructCustomPrincipal(this.User.Identity);
            //Replace the GenericPrincipal in the HttpContext for the current request.
            this.Context.User = cprPrincipal;
        }
    }
