if you could please explain to me one piece of the following code that I don't quite understand I would be grateful:
What does (&(cn=*)({0}={1})) mean in the filter field?
I know that cn means search for the cn attribute and then ADD the result to ({0}={1}).
What is the meaning of ({0}={1})?
Here's the code:
try {
// Create initial context
ctx = new InitialDirContext(env);
Attributes matchAttrs = new BasicAttributes(true);
matchAttrs.put(new BasicAttribute(ldap_id_field, netid));
String attlist[] = {ldap_email_field, ldap_givenname_field,
ldap_surname_field, ldap_phone_field};
// look up attributes
try {
SearchControls ctls = new SearchControls();
ctls.setReturningAttributes(attlist);
NamingEnumeration answer =
ctx.search(ldap_search_context, "(&(cn=*)({0}={1}))", new Object[] {ldap_id_field,netid},ctls);
}
...
