Hi,

I dont have an ldap server, tested this at work without success - but I
may in the wrong server something - can you tell me if this code alone
is enough to purely authenticate against an LDAP server?  Do I need
other key properties - I tried port 389 without success - I get a timed
out error.

    private String initialContext = "com.sun.jndi.ldap.LdapCtxFactory";
    private String authenticationMethod = "simple";
    private String providerUrl = "ldap://ldap:636";

    public LdapAuthentication() {
        super();
    }

    public void authenticate (String username, String password) throws
InvalidUserLoginException {
       DirContext ctx = null;
       try {
           ctx = getContext(username, password);
       } catch (NamingException ne) {
           throw new InvalidUserLoginException(ne.toString());
       }  finally {
           if (ctx != null) {
               try {
                   ctx.close();
               } catch (NamingException ne) {
