I am not able to authenticate a user using LDAP. I have got following details:

LDAP BASE:DC=lab2,DC=ins 
LDAP Bind Account: CN=Ld         


        

Answer 1

Try using this, it worked for me

public static Boolean validateLogin(String userName, String userPassword) {
    Hashtable env = new Hashtable();


    env.put(Context.INITIAL_CONTEXT_FACTORY, "com.sun.jndi.ldap.LdapCtxFactory");
    env.put(Context.PROVIDER_URL, "ldap://" + LDAP_SERVER + ":" + LDAP_SERVER_PORT + "/" + LDAP_BASE_DN);
    env.put(Context.SECURITY_AUTHENTICATION, "simple");
    env.put(Context.SECURITY_PRINCIPAL, userName + "@" + LDAP_SERVER);
    env.put(Context.SECURITY_CREDENTIALS, userPassword);

    DirContext ctx;
    try {
       ctx = new InitialDirContext(env); //throw exception, if username-password not correct
       return true;
    } catch (Exception e) {
        return false;
    }
}
