Hey guys, sorry for bouncing that topic again, but this issue currently is a show stopper
for us. We need to have multi-tenancy for our application, but as it works now it is not
feasible.
So we desparatly ask for your help.

Hello,
we deployed a jsf primfaces application on a JBoss EAP 7.0 System. We have to support
multiple clients using multi tenancy. We followed the instructions of the documentation
[1] to build up a CustomKeycloakConfigResolver.
We configured the web.xml like this:
[web.xml]
<web-app>
...
<security-constraint>
<web-resource-collection>
<web-resource-name>portal</web-resource-name>
<url-pattern>/portal/*</url-pattern>
</web-resource-collection>
<auth-constraint>
<role-name>user</role-name>
</auth-constraint>
</security-constraint>
<security-constraint>
<web-resource-collection>
<web-resource-name>public</web-resource-name>
<url-pattern>/portal/pages/willkommen.jsf</url-pattern>
<url-pattern>/portal/pages/logout.jsf</url-pattern>
</web-resource-collection>
</security-constraint>
<login-config>
<auth-method>KEYCLOAK</auth-method>
</login-config>
<security-role>
<role-name>user</role-name>
</security-role>
...
<context-param>
<param-name>keycloak.config.resolver</param-name>
<param-value>de.sample.security.MandantBasedKeycloakConfigResolver</param-value>
</context-param>
...
</web-app>
As you can see everything under portal is restricted with two exceptions. The code of
MandantBasedKeycloakConfigResolver is straight forward and adapted to the example code
[2]. In our example we consider that the url has a query parameter that provides an id
which we can map to a corresponding keycloak.json file. A sample would be
"https://localhost:8443/SampleApp/portal/pages/willkommen.jsf?kId=1".
After deployment I realized, that the KeycloakConfigResolver is called 44 times (see log
entries [3]). As it turns out the KeycloakConfigResolver.resolve() methode is called for
every resource that is loaded through get requests to display the site. I did not expect
that many invocation, since the resources are not protected.
Can you please tell me if this behaviour is correct? What is my error in adopting the
mulity tenancy sample? How can we prevent/workaround that many calls?
While researching I found a jira https://issues.jboss.org/browse/KEYCLOAK-8616 with a
potentially similar problem. Here they use keycloak to secure a spring boot application
and have troubles when a sso redirection occurs.

Andreas
