Accessing Microsoft AD LDAP through JNDI

Hi,

I want to lookup some names in Microsoft AD LDAP server. I'm using JNDI APIs to connect and lookup names from that LDAP server.
I'm successfully able to make a connection to the LDAP server however while looking up the name it gives me the following exception:

Lookup failed: javax.naming.NamingException: [LDAP: error code 1 - 000020D6: Svc
Err: DSID-031006CC, problem 5012 (DIR_ERROR), data 0 ]; remaining name 'cn=parema'
javax.naming.NamingException: [LDAP: error code 1 - 000020D6: SvcErr: DSID-03100
6CC, problem 5012 (DIR_ERROR), data 0
]; remaining name 'cn=parema'

at Lookup.main(Lookup.java:61)
----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

I'm using the following code to connect to the LDAP:

Hashtable<String, Object> env = new Hashtable<String, Object>(11);
env.put(Context.INITIAL_CONTEXT_FACTORY,"com.sun.jndi.ldap.LdapCtxFactory");
env.put(Context.PROVIDER_URL, "LDAP://CORP.WEYER.PRI");
env.put(Context.SECURITY_PRINCIPAL, "parema@CORP");
env.put(Context.SECURITY_CREDENTIALS, "mycorppassword!");

Context ctx = new InitialContext(env);
// Perform lookup and cast to target type
LdapContext b = (LdapContext) ctx.lookup("cn=parema");

I'm sure that I'm able to connect to the LDAP server as I'm using my corp username and password to connect to it. In case I use any other username and password, it gives me an javax.naming.AuthenticationException.

Please let me know if this is the right way to lookup values from an LDAP server?

Thanks,
Makrand
