Hi there.
Im relatively (its been years) new to LDAP Im sure mine is a basic
newbie problem,
But I need to deliver an LDAP Java coding solution asap.
So...I installed Apache Directory Suite and Studio and loaded the
sevenSeas ldif file,
Brought up Apache Studio, got a connection, scanned the schema entries.
Now, my first LDAP with Java coding try: simply get a context connection
with the
Admin/admin system userid. After that works I need to be able to
rebind? With other
User/passwords for authentication validation then retrieve a few
attributes.
Alas, my 1st coding attempt fails with :
javax.naming.InvalidNameException: [LDAP: error code 34 - Incorrect DN
given : admin (0x61 0x64 0x6D 0x69 0x6E ) is invalid]

And here is my code try:
I suspect it may me the provider url?

// env.put(Context.SECURITY_PRINCIPAL, "cn=S. User,

//String sec_principal = "admin";
String sec_credentials = "admin";
// TODO ? provider url needs an extension
ie..."ldap://10.0.1.10:389/dc=ldap,dc=gruchala,dc=eu";);
String provider_url = "ldap://localhost:10389";;
// Set up the environment for creating the initial
context
Hashtable<String, Object> env = new Hashtable<String,

env.put(Context.INITIAL_CONTEXT_FACTORY,

env.put(Context.PROVIDER_URL, provider_url);
env.put(Context.SECURITY_AUTHENTICATION,sec_authentication);
env.put(Context.SECURITY_PRINCIPAL, sec_credentials);
// specify the username
env.put(Context.SECURITY_CREDENTIALS, sec_credentials);
// specify the password
try {
ctx = new InitialDirContext(env);
System.out.println(ctx.lookup("cn=admin"));
} catch (NamingException e) {
// TODO Auto-generated catch block
e.printStackTrace();

System.err.println("Error exiting...2");
return;
}
// ... do something useful with ctx
System.out.println("... do something useful with ctx");
}
