Bonsoir,
J’essaie de récupérer des données dans un ldap avec spring mais j'ai quelques problèmes dans mon code que je n'arrive pas à résoudre.
Mon code :
-Un fichier ContextSource :

import javax.naming.Context;
import org.springframework.ldap.core.ContextSource;
import org.springframework.ldap.core.support.LdapContextSource;
public class LdapContextSourceFactory {
public static ContextSource getLdapContextSource() throws Exception {
LdapContextSource ldapContextSource = new LdapContextSource();
ldapContextSource.setUrl("ldap://xxxxxxxxxxxxxxxxxxxx:389");
ldapContextSource.setUserDn("anonymous");
ldapContextSource.setPassword("");
ldapContextSource.setBase("cn=admin, dc=xxxxxxx, dc=fr, ou=people");
ldapContextSource.afterPropertiesSet();
return ldapContextSource;
}

- un fichier ressource :

import java.util.Hashtable;
public class Ressources {
//pour strocker nos donnees
Hashtable ht = new Hashtable();

Si j'ai bien compris, je récupère un mauvais dn dans la fonction :
Code:
1
2
3
4
5
6
7
|
private Name buildDn(String uid) {
DistinguishedName dn = new DistinguishedName();
dn.add("ou", "people");
dn.add("uid", uid);
return dn;
} |
Mais si le problème vient bien de là je ne le vois pas, donc si quelqu'un a une idée, je suis preneur.
Merci d'avance.
