Since version 4 ofAmetys, rights are inherited.
If a user has access to the root of a site, he or she will also have access to a sub-heading by inheritance.
This automatic inheritance of rights introduced a difference in behavior between versions 3 and 4 ofAmetys, in the particular case of assigning rights to groups and subsets of groups.
For each inherited rights context, it is now possible to disable rights inheritance.
