Windows Active Directory 2008 And Java

Question

Hi,
I need to do the following.
1. Integrate my application's authentication module with Microsoft Windows Active Directory (Server 2008 Edition).
2. Need to use Kerberos authentication.
Can you please let me know what api can I use? Is there a good tutorial for this ?

Answer 1

Finally managed to resolve the problem.
I tried to do a lot of things reading forums. But this is what worked.
1. create a key store using $ keytool -genkey -keystore /home/rohan/mystore -keysize 1024 -keyalg RSA --- created "mystore" key store. From the cert file I got the information on RSA and encryption of 1024 bits.
2. import the certificate the keystore - $ keytool -import -keystore /home/rohan/mystore -alias primarydc -file DC2K8.cer
3. In the code just added these lines
env.put(Context.PROVIDER_URL, "ldap://myldapserver:389"); // Port 389 on Windows Domain Controller
String keystore = "/home/rohan/mystore";
System.setProperty("javax.net.ssl.trustStore",keystore);
System.setProperty("javax.net.ssl.keyStorePassword","password");
4. Change of Password (code provided by stevead )
StartTlsResponse tls = (StartTlsResponse)ctx.extendedOperation(new StartTlsRequest());
               tls.negotiate();
               ModificationItem[] mods = new ModificationItem[2];
String newQuotedPassword = "\""+password+"\"";
               byte[] newUnicodePassword = newQuotedPassword.getBytes("UTF-16LE");
               mods[0] = new ModificationItem(DirContext.REPLACE_ATTRIBUTE, new BasicAttribute("unicodePwd", newUnicodePassword));
               mods[1] = new ModificationItem(DirContext.REPLACE_ATTRIBUTE, new BasicAttribute("userAccountControl",Integer.toString(UF_NORMAL_ACCOUNT + UF_PASSWD_NOTREQD)));
               ctx.modifyAttributes(userName, mods);
