Java ldap authentication issue

Question

I'm trying to have my custom java application use our Active Directory Server for authentication but I cannot get it to work for some reason. Can anyone see why this is? Here is my method below:

private boolean authenticate(String serverName, String userId, String password) throws NamingException {
    DirContext ctx = null;
    Hashtable env = new Hashtable(11);
    boolean b = false;
    try {
        env.put(Context.INITIAL_CONTEXT_FACTORY,
        "com.sun.jndi.ldap.LdapCtxFactory");
        env.put(Context.PROVIDER_URL, "ldap://servername.org:389");
        env.put(Context.SECURITY_AUTHENTICATION, "simple");
        env.put(Context.SECURITY_PRINCIPAL, "uid="+ userId +",ou=All Users,dc=site,dc=org");
        env.put(Context.SECURITY_CREDENTIALS, password);
        System.out.println("before context");
        // If there isn't a naming exception then the user is authenticated. Return true
        ctx = new InitialDirContext(env);
        //The user is authenticated.
        b = true;
    } catch (NamingException e) {
        System.out.println("the user is not authenticated return false");
        b = false;
    }finally{
        if(ctx != null)
            ctx.close();
    }
    return b;
}

Result:

[12/14/11 16:27:47:746 CST] 0000001f SystemErr     R
javax.naming.AuthenticationException: [LDAP: error code 49 - 80090308: LdapErr: DSID-0C090334, comment: AcceptSecurityContext error, data 52e, vece

Answer 1

Have you tried this way?

//...
env.put(Context.SECURITY_PRINCIPAL, "cn="+ userId +",ou=All Users,dc=site,dc=org");
//...

Also replace

Hashtable env = new Hashtable(11);

with

Hashtable env = new Hashtable();
