Security configuration

You need to define the security configuration in a Config component (authentication and authorization mechanisms).

Read the [documentation]http://www.pac4j.org/docs/config.html).

1. It can be built via a configuration factory (org.pac4j.core.config.ConfigFactory):

public class DemoConfigFactory implements ConfigFactory {

    @Override
    public Config build(final Object... parameters) {
        final SAML2ClientConfiguration cfg = new SAML2ClientConfiguration("resource:samlKeystore.jks", "pac4j-demo-passwd", "pac4j-demo-passwd", "resource:testshib-providers.xml");
        cfg.setMaximumAuthenticationLifetime(3600);
        cfg.setServiceProviderEntityId("http://localhost:8080/callback?client_name=SAML2Client");
        cfg.setServiceProviderMetadataPath(new File("sp-metadata.xml").getAbsolutePath());
        final SAML2Client saml2Client = new SAML2Client(cfg);

        final FacebookClient facebookClient = new FacebookClient("145278422258960", "be21409ba8f39b5dae2a7de525484da8");
        final TwitterClient twitterClient = new TwitterClient("CoxUiYwQOSFDReZYdjigBA", "2kAzunH5Btc4gRSaMr7D7MkyoJ5u1VzbOOzE8rBofs");
        final FormClient formClient = new FormClient("http://localhost:8080/loginForm.jsp", new SimpleTestUsernamePasswordAuthenticator());

        ...

        final Clients clients = new Clients("http://localhost:8080/callback", oidcClient, saml2Client, facebookClient,
                twitterClient, formClient, indirectBasicAuthClient, casClient, parameterClient,
                directBasicAuthClient, new AnonymousClient(), casProxy);

        final Config config = new Config(clients);
        config.addAuthorizer("admin", new RequireAnyRoleAuthorizer<>("ROLE_ADMIN"));
        config.addAuthorizer("custom", new CustomAuthorizer());
        config.addAuthorizer("mustBeAnon", new IsAnonymousAuthorizer<>("/?mustBeAnon"));
        config.addAuthorizer("mustBeAuth", new IsAuthenticatedAuthorizer<>("/?mustBeAuth"));
        config.addMatcher("excludedPath", new PathMatcher().excludeRegex("^/facebook/notprotected\\.jsp$"));
        return config;
    }
}

if the configFactory servlet parameter is used

   <init-param>
      <param-name>configFactory</param-name>
      <param-value>org.pac4j.demo.jee.DemoConfigFactory</param-value>
   </init-param>

2. Or produced via CDI:

@Dependent
public class SecurityConfig {

    @Produces @ApplicationScoped
    private Config buildConfiguration() {
        logger.debug("building Security configuration...");

        final OidcConfiguration oidcConfiguration = new OidcConfiguration();
        oidcConfiguration.setClientId("167480702619-8e1lo80dnu8bpk3k0lvvj27noin97vu9.apps.googleusercontent.com");
        oidcConfiguration.setSecret("MhMme_Ik6IH2JMnAT6MFIfee");
        oidcConfiguration.setUseNonce(true);
        oidcConfiguration.addCustomParam("prompt", "consent");
        final GoogleOidcClient oidcClient = new GoogleOidcClient(oidcConfiguration);
        oidcClient.setAuthorizationGenerator((ctx, profile) -> { profile.addRole("ROLE_ADMIN"); return profile; });

        final FormClient jsfFormClient = new FormClient(
                "http://localhost:8080/jsfLoginForm.action",
                new SimpleTestUsernamePasswordAuthenticator()
        );
        jsfFormClient.setName("jsfFormClient");

        final IndirectBasicAuthClient indirectBasicAuthClient = new IndirectBasicAuthClient(new SimpleTestUsernamePasswordAuthenticator());

        final CasConfiguration configuration = new CasConfiguration("http://localhost:8888/cas/login");
        final CasClient casClient = new CasClient(configuration);

        final List<SignatureConfiguration> signatures = new ArrayList<>();
        signatures.add(new SecretSignatureConfiguration(Constants.JWT_SALT));
        ParameterClient parameterClient = new ParameterClient("token", new JwtAuthenticator(signatures));
        parameterClient.setSupportGetRequest(true);
        parameterClient.setSupportPostRequest(false);

        final DirectBasicAuthClient directBasicAuthClient = new DirectBasicAuthClient(new SimpleTestUsernamePasswordAuthenticator());

        ...

        final Clients clients = new Clients(
                "http://localhost:8080/callback",
                oidcClient,
                formClient,
                jsfFormClient,
                saml2Client, facebookClient, twitterClient, indirectBasicAuthClient, casClient,
                parameterClient, directBasicAuthClient, new AnonymousClient()
        );

        return new Config(clients);
    }
}
