Hi.
I'm trying to understand how a standard Java web app (client) deal
with keycloak roles mechanism.
...
<security-constraint>
<web-resource-collection>
<web-resource-name>App</web-resource-name>
<url-pattern>/some-context/*</url-pattern>
</web-resource-collection>
<auth-constraint>
<role-name>some-role</role-name>
</auth-constraint>
</security-constraint>
<login-config>
<auth-method>KEYCLOAK</auth-method>
<realm-name>demo</realm-name>
</login-config>
<security-role>
<role-name>some-role</role-name>
</security-role>
...
Keycloak has two different role levels: Realm roles and Client
roles.
When I create a new user it can automatically inherit default roles
from its realm.
But I can't refer to realm roles from my client app because by
default there is no relationship between realm roles and client
apps.
I mean a client under the realm is not aware of realm roles. Right?
From the client app user perspective, I have to create the roles for
a specific client app and then associate that role(s) with a given
user (who wants to have access to that client app). Ok! But what can
I do to associate realm roles with a given client app?
I can create a composite role inside the client and associate it
with some realm roles. But I still have to explicitly associate that
client role with each user I want to grant access to that client
app.
Imagine a scenario where you imported thousands of users from a LDAP
server (through User Federation).
Let me explain my scenario:
I'm federating users and roles from an MS AD server. I created a
Role Mapper to import AD groups as Keycloak roles and automatically
create realm roles.
Keycloak imported LDAP groups as realm roles and associated that
roles with each user (according to the group/user association on
LDAP)
But in this scenario the association roles/client app on Keycloak
is missing. Ok, I could choose to import LDAP groups as Client roles
on the LDAP Role Mapper configuration. But I prefer to import as
realm roles. Thus all client app create under this realm will
inherit that roles.
The role mapper worked perfectly! The problem is: How can I use that
roles (imported to realm and associated with each imported user) to
restrict access to a specific client app?
Can some one point me what would be the correct understanding and
the right approach to use imported AD roles into my realm?
