Is there any way to accomplish this while using the rights module? It seems like rights stores user id’s in the table for assigning a role to a user. It can lead to a duplication of id’s in the rigths related tables ect.
Rights extension is a backend module for managing Role Based Access Controll (RBAC) where you can define a "webuser" and a "adminuser" roles. Users are assigned to roles through the AuthAssignment table (and Rights extension do that quiet well).
But maybe you "have to" deal with two different user tables ?
