Best Design for a User/Role Management System?
Here's a software design question I've encountered several times and have never found an ideal solution for (I'm also dealing with it now again.)
Many applications need some form of user/role management. You have base users, groups that these users can belong to (not limited to just one), roles and permissions they have, organizational units, and a whole bunch of properties and other features that are project-specific.
My question is, what ways do people know of and/or have experience with to design and build a really dynamic, flexible user management system? Are there any design patterns you know of that really help?
Because every organization has different needs, you should adapt your design while designing and building a dynamic and flexible user management system.
Role Based Access Control (RBAC) is a common approach. In this model, users are assigned roles, and the roles have corresponding permissions. As a result, instead of granting permissions directly to users, permissions are granted to roles. Users who are allocated to a role inherit the permissions associated with that role.
Role hierarchies can be used to improve efficiency and scalability. Higher-level roles in a role hierarchy inherit permissions from lower-level ones. As a result, when a modification is made to a higher-level position, it is propagated to all lower-level roles.
