Forms Authentication

I have a website which uses Forms authentication.  I would like for a couple folks, mainly me, to be authenticated with my AD user id of the PC I am on.  Currently I  have code in the login page which compares the Request.LogonUserIdentity.Name.ToString to "Domain\Me"  and if true it sets a cookie with my name and then redirects to the calling page.  Is this method ok?  Is there a more preferred way of associating my AD account with a forms user id account? Here is the code I am using.
Dim myid As String = Request.LogonUserIdentity.Name.ToString If myid = "USC\blabla" Then FormsAuthentication.SetAuthCookie("blabla", True) FormsAuthentication.RedirectFromLoginPage(Request.LogonUserIdentity.Name.ToString, True) End If

thanks
