How to create a new Active Directory account with Java (via JNDI)?

Question

Is it possible to create a new user in AD rom Java via JNDI?

I tried through reliable Google, but didn't come up with anything - maybe I searched Google using the wrong terminology (JNDI Active Directory Create User).

Any advice would be greatly appreciated.

Current status: I connected to AD through my Java code and can change the attributes of existing AD accounts; Next, I would like to be able to create AD users from Java / JNDI.

I am using http://forums.sun.com/thread.jspa?threadID=582103 and I have made sure that my account has the correct privileges to create an AD account and I am using LDAPS.

It's complicated. You cannot set passwords unencrypted, and if you have not configured your entire cryptographic structure, you cannot use LDAPS, so you need to use Kerberos.

// KRB5 connection details:
    System.setProperty("java.security.krb5.kdc", "domain.com");
    String username = "[e-mail]";
    String realm = "DOMAIN.COM";
    System.setProperty("java.security.krb5.realm", realm);
    System.setProperty("java.security.krb5.debug", "true");
    System.setProperty("sun.security.krb5.debug", "true");

// standard JNDI LDAP stuff:
    env.put(Context.INITIAL_CONTEXT_FACTORY, "com.sun.jndi.ldap.LdapCtxFactory");
    env.put(Context.SECURITY_AUTHENTICATION, "simple");
    env.put(Context.PROVIDER_URL, "ldap://dc01.domain.com:389");
    env.put(Context.SECURITY_PRINCIPAL, username);       
    env.put(Context.SECURITY_CREDENTIALS, "abcd1234");

    ctxt = new InitialLdapContext(env, new Control [0]);

// kerberised connection details:
    LoginModule module;
    module = (LoginModule) Class.forName("com.sun.security.auth.module.Krb5LoginModule").newInstance();
    Subject subject = new Subject();
    Map<String, String> options = new HashMap<String, String>();
    Map<String, Object> sharedState = new HashMap<String, Object>();

    sharedState.put("javax.security.auth.login.password", properties.getProperty("ad.passwd").toCharArray());
    sharedState.put("javax.security.auth.login.name", username);
    options.put("principal", username);
    options.put("storeKey", "true");
    options.put("useFirstPass", "true");

    options.put("debug", "true");

    module.initialize(subject, null, sharedState, options);
    module.login();
    module.commit();       


// now create a user account:
    Subject.doAs(svc.getSubject(), new PrivilegedExceptionAction<Object>() {

            @Override
            public Object run() throws Exception {

                try {
                    String password = "\"Password1\"";
                    final Hashtable<String, String> env = svc.getEnvironment();
                    env.put(Context.SECURITY_AUTHENTICATION, "GSSAPI");
                    LdapContext ctxt = new InitialLdapContext(env, new Control[0]);
                    ModificationItem[] mods = new ModificationItem[1];
                    mods[0] = new     
                    ModificationItem(DirContext.REPLACE_ATTRIBUTE, new              
                    BasicAttribute("userPassword", password.getBytes("UTF-16LE")));
ModificationItem(DirContext.REPLACE_ATTRIBUTE, new     BasicAttribute("userAccountControl", Integer.toString(UF_NORMAL_ACCOUNT + UF_PASSWORD_EXPIRED)));
                    ctxt.modifyAttributes(dn, mods);
                }
                catch (NamingException e) { 
                    System.out.println("Failed to set password.");
                    e.printStackTrace();
                }
                return null;
            }
