Search Active Directory Entries without password authentication

Question

JNDI, Active Directory
I am newbie to JDNI and Active Directory.
I am trying to create a Web Application
which provides domain users with the information
of the Active Directory group user are belonging.
I know how to access Active Directory and search Entries
with JNDI like below codes.
Hashtable env = new Hashtable();
env.put(Context.PROVIDER_URL, "LDAP://URL:389");
env.put(Context.INITIAL_CONTEXT_FACTORY, "com.sun.jndi.ldap.LdapCtxFactory");
env.put(Context.SECURITY_AUTHENTICATION,"none");
env.put(Context.REFERRAL, "follow");
env.put("java.naming.ldap.version" , "3" );
env.put(Context.SECURITY_PRINCIPAL, "uid=admin,ou=system");
env.put(Context.SECURITY_CREDENTIALS, "secret");
.....But I want know how to search Entries without Active Directory password
because I don't tell users their Active Directory password.
I don't have any idea. Could you give me good idea?
Sorry for my English. Thank you.

Answer 1

It means to allow "Anonymous LOGON" and "Everyone" users to search entries in AD, I think.Sorry, can't help. In OpenLDAP it meansallow * searchor possiblyallow * auth
You mean that if I do it, will the codes below be unnecessary in Java?That's not only what I meant, it is what I said, concerning the principal and credentials lines.
You don't need the SECURITY_AUTHENTICATION line, I never use it with LDAP whether I'm providing credentials or not (and in the cases where you are supplying the principal and credentials, it certainly doesn't make any sense to specify 'none'.)
