I don't think Keycloak integration code can be
worked to be a common utility.
It seems to me that you would need a specific security
realm implementation from where you could just return an
authorized identity as a result of parsing the SAML assertion.
Here is what we have in Keycloak [1]. As you can see, we are
basically trusting a KeycloakPrincipal, previously created by
the keycloak adapter, and creating an authorization identity
from it. We don't re-authenticate the user.
So when pushContext is called, you could use
serverauthenticationcontext and the CBH to ask Elytron for a
security identity. See [2]. In this last example, we pass the
previously authenticated principal via EvidenceVerifyCallback.
I
think this might work for you.

Later we complete authentication in Elytron and set the token as a credential into the identity. It is worth mention that in Keycloak integration, the adapter is a Elytron HTTP Authentication Mechanism, so we don't deal directly with the security domain but with the callback handler.In Keycloak integration we have a specific security realm implementation that expects a principal previously authenticated by a keycloak adapter (e.g.: using SAML or OIDC) and builds an authorized identity based on it. Basically, what this security realm does is populate the authorized idenitty with information from tokens.
Regarding ElytronSecurityDomainContextImpl, is method pushContext called after a call to isValid ? If so, the security domain should be set with the security identity and you don't even need to keep that ThreadLocal ...
Thanks Pedro . Do you think the keycloak Elytron integration code can be improved or changed to a common utility to convert the principal to an Elytron identity?
Can you please point me the integration code or some Elytron example code snippet to build this authorized identity from a authenticated principal ?

Just added Pedro in CC so see if he has any suggestions - this is sounding similar to the problems he would have needed to handle when he added support for KeyCloak integration using the Elytron APIs.
Although the reported problem we are working on is in the context of access to the token it does currently sound that there is a missing pre-requisite step of tying the authentication to Elytron to we can populate a SecurityIdentity. But this does not sound like the first time we have needed to approach this.

So the validation is within Apache CXF - is there an end result to this validation where you have access to everything you need where we could perform some additional steps?
After Apache CXF validation, we can get a LoginContext from CXF's exchange message : https://github.com/apache/cxf/blob/master/core/src/main/java /org/apache/cxf/security/Login SecurityContext.java
Can we do something to convert it to an Elytron authenticated identity ?
Or we have to hook/replace something with Elytron in CXF's validation to make this work ?

It sounds to me then that the place to start is within the SAML validation, this is effectively an authentication step so should be ported over to an Elytron based authentication - the end result of the authentication would then be the required SecurityIdentity to propagate from container to container.

I am currently gathering together some information regarding how the JCA subsystem handles the requirement of populating a Subject for propagation into a resource adapter, however there is a general question about what is attempting to be achieved here.
Once an EJB is secured using WildFly Elytron the associated identity is not accessed as a Subject instead it is accessed a SecurityIdentity the current SecurityIdentity can always be retrieved by calling the current SecurityDomain: -
The SecurityIdentity has some similarity with the Subject in that amongst other things it also contains a collection of public credentials and a collection of private credentials: -
So I think the very first question is has the SecurityIdentity been correctly populated with any delegated credentials? If not that is going to be a pre-requisite for any follow on steps regardless.
Then secondly what is it that is making use of this identity? Why can't it be ported to make use of the Elytron authentication client APIs which amongst other things provide support for delegation from the current identity.
If we need to we can look at a conversion to a Subject but we are only doing that where it is really required.
We don't have the SecurityIdentity populated, there is only principal and subject created by jbossws/CXF's saml validator.
We need to convert the subject/principal to Elytron's SecurityIdentity or something else, then later on EJB subystem with Elytron
security can retrieve this authenticated info without check it twice. So we'd like to know how can we convert a subject/principal
to Elytron's SecurityIdentity and let Elytron know this is already authenticated and authorized.
Thanks,
Jim

Hi Darran,
We are helping look at a customer issue which requires propagate the authenticated subject from webservice subsystem to
ejb subystem. With old security domain , we can do this with creating a subject :
@Override
public void pushSubjectContext(final Subject subject, final Principal principal, final Object credential) {
AccessController.doPrivileged(new PrivilegedAction<Void>() {
public Void run() {
SecurityContext securityContext = SecurityContextAssociation.getSecurityContext();
if (securityContext == null) {
securityContext = createSecurityContext(getSecurityDomain());
setSecurityContextOnAssociation(securityContext);
}
securityContext.getUtil().createSubjectInfo(principal, credential, subject);
return null;
}
});
}
After Elytron, what is the equivalent thing to do this then ejb can retrieve this security without check this twice ?
Thanks,
Jim
