URGENT: java.net.ConnectException: Connection refused: connect <LDAP>

[bouchi...@free.fr]

Hello,

I want to connect to a ldap server .. but i have this error:
javax.naming.CommunicationException: loupo:389. Root exception is
java.net.ConnectException: Connection refused: connect

With a program in C, there's no problem.

The LDAP server is running on loupo on port 389.
The server is a Linux machine ... the server has been insatlled with
openldap rpm.

This is my program :

Properties env = new Properties();

env.put(javax.naming.Context.INITIAL_CONTEXT_FACTORY,"com.sun.jndi.ldap.LdapCtxFactory");
env.put(Context.PROVIDER_URL, "ldap://loupo:389/");

env.put(Context.SECURITY_AUTHENTICATION, "simple");
env.put(Context.SECURITY_PRINCIPAL, "o=admin, c=fr");
env.put(Context.SECURITY_CREDENTIALS, "password");
env.put("java.naming.ldap.version", "2");

DirContext ctx;
try {
ctx = new InitialDirContext(env);

//SearchControls ctrl = new SearchControls();
//ctrl.setSearchScope(SearchControls.SUBTREE_SCOPE);

//NamingEnumeration answer = ctx.search("o=Paul, c=FR", "sn=*",ctrl);

} catch (NamingException e) { e.printStackTrace();
}

I try to change the properties (env.put) but no result ...
The LDAP server is only access by the administrator ( the Dn is
"o=admin, c=fr"
and pass is "password"). So I can't connect to the server in anonymous
mode.

Someone have any idea ??

Thanks.
