That's one way to do it, yes. We do almost the same, except that our groups live in the ZODB and are created when we create a site using the configurator. However, we have an ASP solution, so we need to make sure that if User U is in Group G in Site 1, then he is not in Group G in Site 2. You might not have this requirement, so doing global declarations is fine. Having the groups in the ZODB allows you also to just set the members on the group. The framework does the rest. Again, this might not be desirable for external users. > next steps: > -users are located outside of ZODB (lets say a simple mysql table with > login, password, group as attributes), so i would write a PAU > Authenticator Plugin.

You can have that info in the principal info of the auth plugin. > im i thinking right here? i just want to make sure i unterstood this, > before work begins. Yep, looks all good.
