I don't agree at all. If User Groups and Client Groups exist, there is no
need for role namespaces. It is stupid to have to create another concept
(role namespace) to define the roles one specific client or a group of
clients expects.
I've never the concept of realm and client roles. It's been difficult to
explain and strange to use. I've always just used realm roles. It's a
strange and limiting concept. Introducing client groups with further places
to define roles just makes matters even worse. Now users have two go 3
different places to define roles:
* Realm
* Client Groups
* Clients
What happens if a client group and a client both have the same role by the
way?
It's a strange limitation. At least personally if I was using Keycloak I
would simply use realm roles alone and define my own hierarchy with a
delimiter.
It's much better to have a single place to define roles, under the roles
tab. Then allow users can define the namespaces/hierarchy they want.
Role namespaces are easier to deal with and at the same time more flexible.
I just don't see any reason why we would have roles specific to a client or
client group.
If you combine Role namespace and Groups you can define things like a
group admin role. Roles that mean something to the group.
Each Client Group would have some default roles defined. i.e. roles

A Client Group could have a "client group admin" role. If a user has that
role it can manage clients in the group. Another role might be "client
membership admin". This role allows a user to add or remove clients from
the group.
Conversely, user groups could have a "user group admin". When granted,
this role allows a user to manage users in the group. YOu can also do
things like define a "Manager" role for the group. This "Manager"
would be
granted "user group admin" privileges and also granted access to other
systems like "HR", "Attendence", "Benefits", etc.
I think this permission concept should be built into Keycloak as it is a
core feature. I'll write u a separate email about this.
This is another reason why we need role namespaces. With a role namespace
we can define internal roles that then don't end up conflicting with users
own roles. For example as we have a role admin atm users can't define their
own admin role and will have to name it differently.
I think the fact that we have internal abstract clients to be able to
create a namespace for internal admin roles speaks for itself.

Again, I think role namespaces are redundant.
A client can define a set of roles that it offers. A service account (the
client) can have roles associated with it so it can do certain actions.
Some will want to have roles associated with a client (email-user), but
others have organizational wide roles (manager, sales-guy, etc..). Role
namespaces can deal with both, but client roles can't.
