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.
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.
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 ...
