Searching LDAP

Question

I am trying to search LDAP for email addresses but am getting a javax.naming.NameNotFoundException when I know that the name I am using exists. Here is my code:
Hashtable hashtableEnvironment = new Hashtable();
     hashtableEnvironment.put(
Context.INITIAL_CONTEXT_FACTORY,
"com.sun.jndi.ldap.LdapCtxFactory"
     hashtableEnvironment.put(
Context.PROVIDER_URL,
"ldap://LDAP.SERVER:389/o=organization"
     try {
     // Create the initial context
     InitialDirContext context = new InitialDirContext(hashtableEnvironment);
          String[] attrIDs = {"cn,email"};
          SearchControls ctls = new SearchControls();
          ctls.setReturningAttributes(attrIDs);
     NamingEnumeration ne = context.search("o=City of Vancouver", "cn=Darrin", ctls);
          while (ne.hasMore())
               System.out.println((String)ne.next());
I very much appreciate the help if anyone sees something obvious that I am doing wrong here.

Answer 1

That depends on how your entry is stored in the LDAP server. So do you have a entry with dn:
cn=Darrin,o=City of Vancouver,o=organization
in your directory?
Try using some simple free Java tool to access your directory, such as downloading LDAP browser from
http://www.iit.edu/~gawojar/ldap/
I found the above tool helps alot when I developing LDAP programs.
