JAAS

You can use your own `javax.security.auth.spi.LoginModule` implementation for authentication and authorization in Management Center.

Setting Up the JAAS Security Provider

To set up JAAS, you need to configure settings either in the UI or the mc-conf tool.

UI
mc-conf

You must be an admin user.

To set up the local security provider in the UI, go to Settings > Security Providers > JAAS.

JAAS Configuration

Use the jaas configure task. For help, use the -h flag or see Management Center Configuration Tool.

Linux and macOS

mc-conf.sh jaas configure

Windows

mc-conf.bat jaas configure

Login Module Class: Fully qualified class name of your javax.security.auth.spi.LoginModule implementation.
Admin Group: Members of this group have admin privileges on the Management Center.
User Group: Members of this group have read and write privileges on the Management Center.
Read-only User Group: Members of this group have only read privilege on the Management Center.
Metrics-only Group: Members of this group have the privilege to see only the metrics on the Management Center.

Creating and Managing Users

To create and manage additional users, you must configure them in your JAAS login module.

When creating users, be sure to give them a valid role. See User Management.

The following is an example implementation. Note that this example returns two java.security.Principal instances; one of them is the username and the other one is a group name, which you will use when configuring JAAS security as described above.

import javax.security.auth.Subject;
import javax.security.auth.callback.Callback;
import javax.security.auth.callback.CallbackHandler;
import javax.security.auth.callback.NameCallback;
import javax.security.auth.callback.PasswordCallback;
import javax.security.auth.login.LoginException;
import javax.security.auth.spi.LoginModule;
import java.security.Principal;
import java.util.Map;

public class SampleLoginModule implements LoginModule {
    private Subject subject;
    private String password;
    private String username;

    @Override
    public void initialize(Subject subject, CallbackHandler callbackHandler, Map<String, ?> sharedState, Map<String, ?> options) {
        this.subject = subject;

        try {
            NameCallback nameCallback = new NameCallback("prompt");
            PasswordCallback passwordCallback = new PasswordCallback("prompt", false);

            callbackHandler.handle(new Callback[] {nameCallback, passwordCallback });

            password = new String(passwordCallback.getPassword());
            username = nameCallback.getName();
        } catch (Exception e) {
            throw new RuntimeException(e);
        }
    }

    @Override
    public boolean login() throws LoginException {
        if (!username.equals("emre")) {
            throw new LoginException("Bad User");
        }

        if (!password.equals("pass1234")) {
            throw new LoginException("Bad Password");
        }

        subject.getPrincipals().add(new Principal() {
            public String getName() {
                return "emre";
            }
        });

        subject.getPrincipals().add(new Principal() {
            public String getName() {
                return "HazelcastMCAdmin";
            }
        });

        return true;
    }

    @Override
    public boolean commit() throws LoginException {
        return true;
    }

    @Override
    public boolean abort() throws LoginException {
        return true;
    }

    @Override
    public boolean logout() throws LoginException {
        return true;
    }
}
