Is there a way to retrieve the maxPwdAge value from the group policy?

I use JNDI to look up users in MS Active Directory (LDAP). This works fine - but I also want to know the maximum password age for the user which is to be found in the policy.

I have seen different articles about domainDNS but nothing really useful.

Here is some of the code that I wrote so far - it doesn't work :

****************************************

Hashtable env = new Hashtable(11);

env.put(Context.INITIAL_CONTEXT_FACTORY,
"com.sun.jndi.ldap.LdapCtxFactory");

env.put(Context.PROVIDER_URL, "ldap://ad_server:389/DC=company,DC=com");

env.put(Context.SECURITY_PRINCIPAL, "CN=admin,OU=orgunit,DC=company,DC=com");

env.put(Context.SECURITY_CREDENTIALS, "adminpwd");




try {



// Create the initial directory context

DirContext ctx = new InitialDirContext(env);



// Ask for all attributes of the object

Attributes attrs = ctx.getAttributes("cn=some_name, ou=orgunit");


// Find the maximum password age ("maxPwdAge") and print it

out.println("maximum pwd age: " + attrs.get("maxPwdAge").get());



// Close the context when we're done

ctx.close();

} catch (NamingException e) {

out.println("Problem getting attribute: " + e);

}

}

****************************************

By the way - I code JSP! Not that I should matter (?)...

Can someone please help me...? Thanks!
