[keycloak-user] KeycloakSecurityContext returns NULL using Tomcat Adapter

[LEONARDO NUNES]

Hi everyone,

This problem might stop me from using Keycloak, it's been a week since i'm trying to find a way to make it work but I couldn't find any.
If it's a container issue, is there another way to make it work?

What can I do to access information from the current logged in user at a page that is not secured at the security-contraints at web.xml?
The code below returns null at pages that is not secured, even when the user is logged in.
If the application is deployed to Wildfly it works, but it doesn't work at Jboss EAP and Apache Tomcat.

(KeycloakPrincipal) req.getUserPrincipal()
Or
(KeycloakSecurityContext) req.getAttribute(KeycloakSecurityContext.class.getName())


All of our applications is deployed to Jboss EAP and Apache Tomcat.

This is down to the fact that there are differences between different containers. In reality you can only guarantee that KeycloakSecurityContext as long as the request requires authentication. Add a security-constraint for movies and you're fine.

Stian,

I have an application deployed on Tomcat 7 using the Tomcat Adapter.
When i'm logged in and I go to a non-secured URL, KeycloakSecurityContext returns null.
I deployed the same application to the Keycloak Standalone Server, there I don't have this problem.

At Tomcat the code below returns null when called from /movies/, and works when called from /article/
At Keycloak Standalone Server /movies/ and /article/ works fine.
(KeycloakSecurityContext) request.getAttribute(KeycloakSecurityContext.class.getName());

Why is this happening?

In my web.xml I have only one security-constraint securing /article/*

WEB.XML:
<security-constraint>
    <web-resource-collection>
        <web-resource-name>Articles</web-resource-name>
        <url-pattern>/article/*</url-pattern>
    </web-resource-collection>
    <auth-constraint>
        <role-name>user</role-name>
    </auth-constraint>
</security-constraint>
