security model with regards to aquisition
I have a folder that has restricted access. In a parent folder I have a DTML method that accesses a property of the folder. A browser that has not been autheticated for viewing the folder can still view use the aquired method in the folder, ie they type http://server.com/RestrictedFolder/parentMethod and it works!!! This seems counter intuitive to me. Either you have access to a folder or you do not. Why is this the case and should it be? In any case how do I make sure users can not do the above unless authenticated?

Me too. Note that this has nothing to do with acquisition. A Public method of the folder could also access a property of the folder.
Either you have access to a folder or you do not.
Well, there are many types of access. But I think it should be possible to disacble access to a folder's properties through the "Access contents information" permission.

This is a bug in the validation logic. The current rules allow access to objects that don't have __roles__ attributes and that are not acquired. The reason is that it is assumed that you have to have access to the container to get the object, but this is not always true. I will fix this today and check the fix in, so it will be available via the public CVS. The fix will also be in the next release. The fix will add a check for parent roles even if an object is not acquired. A possible work around is to use an expression and name the folder when you access properties to force access to the folder to be checked: <!--#var "theSecretFolder.aProperty"--> Jim -- Jim Fulton mailto:jim@digicool.com Python Powered!
