> The current Jetspeed security role/group model *technically* supports a hierarchical relationship.
> In practice though, this isn't used really, nor do the j2-admin portlets support it through the UI.
> Furthermore, the hierarchical relationship is based on a specific (preferences) hierarchy naming which really doesn't fit well (better said: not at all) with a backend like LDAP.
> The current model simply cannot be used with LDAP for using role-group relationships.
> A typical use-case requiring a more simple and straighforward solution:
> - defining organisation divisions and subdivisions as groups and defining a parent-child relationship between them
> - a user belonging to a division group then also belongs to any subdivision group of that division
> - the same goes for roles, the user could automatically inherit the roles assigned to the subdivision group. 
> As AFAIK the hierarchical relationship model isn't used at all right now, this issue will resolve its complexity and limitation by replacing it with "flat" parent-child relationships:
> - only support non-hierarchical groups and roles
> - allow a group or role needs to be defined as child of another group or role
> - just need a security-role-role and security-group-group table (and corresponding LDAP mapping)
> - check/enforce no circular references can be created
> - adding UI support for this will be rather easy: we already have support for the group-role relationships, this is just more of the same
