[opencms-dev] ACL logic

[Claus Priisholm]

Not sure I follow exactly what it is you are trying to do, but remember 
that explicitly denying a permission is different from removing the 
permission.
If you explicitly deny a permission then it cannot be overridden whereas 
if you remove (uncheck in the UI) a permission on the folder, then you 
can allow it for a file inside the folder (by checking it in the UI).
