You will probably want to change the helper functions to set some
additional attributes in the virtual directory so that you don't have
to fiddle with the Internet Service Manager GUI all the time. I use
the following to get integrated authentication for an intranet
application and then I check get_request().get_environ('LOGON_USER').

Pseudo-patch:
+
+def set_authentication(params, options, webdir=None):
+    if webdir:
+        webdir.AuthNTLM = True
+        webdir.AuthAnonymous = False
+        webdir.SetInfo()
@@
     vd = install.VirtualDirParameters(Name=name,
                                       Description=description,
                                       ScriptMaps=sm,
-                                      ScriptMapUpdate='replace')
+                                      ScriptMapUpdate='replace',
+                                      PostInstall=set_authentication)
