I am testing the SharePoint navigation with this setup.
Root-Site `All have access` ----SubSite1 `UserA does not have access` --------SubSite1/Pages/default.aspx `inherits permissions from SubSite1`
If I create a heading or link in the Navigation Settings which refers to SubSite1 it will not be shown to UserA, which is correct behaviour.
But if I create a heading or link in the Navigation Settings to SubSite1/Pages/default.aspx it will be shown to the UserA
Why is this? Is this a shortcoming of SharePoint? In that case how do I make PortalSiteMapProvider to also security-trim pages?
