Remote Authentication Naming Service Not Found

Question

Hey everybody,
I found this thread:
http://swforum.sun.com/jive/thread.jspa?threadID=54004
That thread mentions (or implies) there is something different that must be accomplished when performing remote authentications vs local authentications but never actually states what is different.
Anyhow, I am attempting to perform a remote authentication, and am running into problems. I have taken the code listed in the above thread and modified it for my usage, with a few modifications. However, I keep getting this error:
[#|2006-02-13T15:50:56.321-0500|INFO|sun-appserver-pe8.1_02|javax.enterprise.system.stream.out|_ThreadID=25;|ERROR: updateNamingTable : Naming Service is not available.

        at ...When I connect to the service via http://myserver.mydomain.tld/amserver/namingservice I recieve a message that looks like:
Webtop 2.5 Platform Low Level request servletWhich indicates it is running properly. I also am using the AMConfig.properties that is running on the server to pull my values and my code (listed below) prints out all the values it reads. I am using the base dn for the orgname as indicated in various documentation.
My code looks like:
    public boolean login(String username, String password) {
        try {
            ResourceBundle resources = ResourceBundle.getBundle("AMConfig");
            String orgname = null;
            Properties props = new Properties();
            Enumeration keyEnum = resources.getKeys();
            while ( keyEnum.hasMoreElements() ) {
                String key = (String) keyEnum.nextElement();
                String value = (String) resources.getString(key);
                props.setProperty(key, value);
                if ( key.equalsIgnoreCase("com.iplanet.am.defaultOrg") ) {
                    orgname = value;
                this.getFacesContext().addMessage(null, new FacesMessage(key + " = " + value));
            SystemProperties.initializeProperties(props);
            // Authenticate the user and obtain SSO Token
            AuthContext lc = null;
            lc = new AuthContext(orgname);
            lc.login();
            while (lc.hasMoreRequirements()) {
                Callback[] callbacks = lc.getRequirements();
                for (int i = 0; i < callbacks.length; i++) {
                    if (callbacks[i] instanceof NameCallback) {
                        NameCallback nc = (NameCallback) callbacks;
nc.setName(username);
} else if (callbacks[i] instanceof PasswordCallback) {
PasswordCallback pc = (PasswordCallback) callbacks[i];
pc.setPassword(password.toCharArray());
} else {
log("Unknown Callback: " + callbacks[i]);
return false;
lc.submitRequirements(callbacks);
if (lc.getStatus() != AuthContext.Status.SUCCESS) {
log("Invalid credentials");
return false;
// Obtain the SSO Token
token = lc.getSSOToken();
log("SSOToken: " + token.getTokenID());
log("User DN: " +
token.getPrincipal().getName());
// Obtain AMUser object
db = new AMStoreConnection(token);
user = db.getUser(token.getPrincipal().getName());
// Get the attributes and display them
log("Attributes: " + user.getAttributes());
} catch (Exception e) {
this.getFacesContext().addMessage(null, new FacesMessage("An exception occurred, unable to login.", e.getMessage()));
e.printStackTrace();
return false;
Any ideas?
Thanks!

The most common reason for this error is improper
communication with your LDAP server . Is your DS
setup correctly and are you able to authenticate
using amadmin ?Yes, our DS is setup correctly and I am able to authenticate using amadmin.
