Problem with LDAP query

[Dan Grindstaff]

I have a simple java LDAP client that is throwing an error 'Missing 'equals'; remaining name '''. I have posted the code below. I know it must be something simple I am missing. Please advise.

  import javax.naming.*;
import javax.naming.directory.*;
import java.util.Hashtable;

public class SimpleQuery {

    public static void main(String[] args) {

        //if (args.length != 2) {
        //  System.out.println("Syntax: SimpleQuery query attribute");
        //  return;
       // }

        //String query = args[0];
        String query = "APUSTS00001";
        //String query = args[1];
        String attribute = "Welcome05";
        StringBuffer output = new StringBuffer();

        try {
            Hashtable env = new Hashtable();
            env.put(Context.INITIAL_CONTEXT_FACTORY, "com.sun.jndi.ldap.LdapCtxFactory");
            env.put(Context.PROVIDER_URL,"ldap://withheld;);// This is your ldap URL
            env.put(Context.SECURITY_AUTHENTICATION, "simple");
            env.put(Context.SECURITY_PRINCIPAL,"CN=bi_lms_bnd,OU=System Account,OU=NonIndividualAccounts,OU=CHIHQ,DC=americas,DC=astellas,DC=net");//DN
            env.put(Context.SECURITY_CREDENTIALS,"withheld");//This is password
            DirContext context = new InitialDirContext(env);

            SearchControls ctrl = new SearchControls();
            ctrl.setSearchScope(SearchControls.SUBTREE_SCOPE);
            NamingEnumeration enumeration = context.search("", query, ctrl);
            while (enumeration.hasMore()) {
                SearchResult result = (SearchResult) enumeration.next();
                Attributes attribs = result.getAttributes();
                NamingEnumeration values = ((BasicAttribute) attribs.get(attribute)).getAll();
                while (values.hasMore()) {
                  if (output.length() > 0) {
                    output.append("|");
                  }
                  output.append(values.next().toString());
                }
            }

        } catch (Exception e) {
            e.printStackTrace();
        }
        System.out.print(output.toString());
    }

    public SimpleQuery() {}
}  

NOTE: The problem appears tro be on line 34, NamingEnumeration enumeration = context.search("", query, ctrl);

This issue goes quite a bit beyond the beginners' level. Moving to "Java in General".

I don't nothing about LDAP, but I was looking at your code and I saw this:

env.put(Context.SECURITY_PRINCIPAL,"CN=bi_lms_bnd,OU=System Account,

By the error message, I think that your problem is that space in System Account.

The problem with your code was only the variables you were submitting...

String query = "uid=cpare";  // Must be in the form of an LDAP attribute (uid=cpare)
String attribute = "cn";  // The Attribute you would like the LDAP server to return (mail, cn, sn)

If your not sure about the LDAP attributes, download the LDAPBrowser from Softerra, it's free and will allow you to walk the LDAP environment like folders on a computer. it also shows all the attributes available to your ID (remember that many attributes are unlocked based on security).

While I am here I would also suggest breaking out the PROVIDER_URL information and setting these values as Strings to keep things easier to find in the future

        String strLDAPServer = "myserver.domain.com:389";
        String strBaseDN = "dc=something,dc=com";
        env.put(Context.PROVIDER_URL,"ldap://" + strLDAPServer + "/" + strBaseDN);  //LDAP URL
