Re-enabling Permission Inheritance
It it possible to explicitly turn on/off permission inheritance for any node in the permissions hierarchy?
Currently it is possible to change from 'inherited' to 'specific' (green or red) for any given role vs permission. Once it is set to specific seems to be no longer possible to set that permission back to 'inherited'
Accepted answer
Not sure what version of product you are referring to.
In Web client, if you go to team area and hover on the specific permission(which you have set to specific), you would see 4 icons, the first one is 'Inherited permissions from Parent area(clear override), click that would restore the Inheritance. I saw this behavior on 6.0.2 and over.
