Problems With Declarative Security With a Custom Login Module (Doc ID 1954552.1)

Symptoms

When it's checked the caller roles via SessionContext within an EJB, everything works fine. The CallerPrincipal are set well and the isCallerInRole() returns what is expected. But when declared, some EJB with @DeclareRoles() or @RolesAllowed(), the getCallerPrincipal() still return the right value but the isCallerInRole()-Method always return false. It doesnt matter what EJB is declared.

DeclarativeSecurity

-----------------------------

package org.ora.security;

import javax.annotation.Resource;
import javax.annotation.security.DeclareRoles;
import javax.ejb.SessionContext;
import javax.ejb.Stateless;
import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.Produces;
import javax.ws.rs.core.MediaType;

@Path("declarativesecurity")
@Produces(MediaType.APPLICATION_JSON)
@Stateless
//@DeclareRoles("role1")
public class HelloDeclarativeSecurityResource {

    @Resource
    private SessionContext sessionContext;

    @GET
    @Path("/hello")
    public String getHello() {
        System.out.println("callerPrincipal: " + sessionContext.getCallerPrincipal());
        System.out.println("isCallerInRole(role1): " + sessionContext.isCallerInRole("role1"));
        return "hello";
    }
}

Steps:
------------
- Set the following Java-Options in your weblogic start script (-Dwaspsrvfw.security.loginmodule=

MyWeblogicSecurityLoginModule -Dwaspsrvfw.security.token.header.key=SecurityAssertion)
- Do the following configurations with the weblogic console:
 - add group "role1"
 - add global role "role1"
 - set in "role1" as restriction the group "role1" (associate role1 with group role1)
- start weblogic and deploy the project
- call the REST-Service with the following URL:

http://localhost:7001/HelloDeclarativeSecurity/declarativesecurity/hello
 Important: Set the following HTTP-Header "SecurityAssertion: user1;role1"
- Now everything should be fine. On system out you should see the following output:

 callerPrincipal: user1
 isCallerInRole(role1): true

- Now add the annotation @DeclareRoles("role1") to the class HelloDeclarativeSecurityResource,

deploy again and do the same HTTP-Request. Now you should see the following output on system out:

 callerPrincipal: user1
 isCallerInRole(role1): false

 Error: It's expected "true" here .
