How to connect to AD/ldap with TLS

Currently Being Moderated
I have a windows 2008 R2 server installed AD.

After server hardening. I am not able to connect to the AD. After I do the search and find , any none-secured ldap connection will failed.

I am using the following to connect

          String ldapHost = "ldap://Test.local:389";
          Properties props = new Properties();

          //props.put(Context.SECURITY_PROTOCOL, "ssl");
          props.put(Context.SECURITY_AUTHENTICATION, "simple");
          props.put(Context.SECURITY_PRINCIPAL, "" + userName);
          props.put(Context.SECURITY_CREDENTIALS, "" + password);
          props.put(Context.PROVIDER_URL, ldapHost);
          try {
               DirContext ctx = new InitialDirContext(props);
               return true;
          } catch (NamingException e) {
               log.error("Failed Login, login userName:" + userName + ".", e);
          } catch (Exception e){
               log.error(e, e);

Here is the error:
ERROR [main] ( - Failed Login, login userName:test\test.
javax.naming.AuthenticationNotSupportedException: [LDAP: error code 8 - 00002028: LdapErr: DSID-0C0901FC, comment: The server requires binds to turn on integrity checking if SSL\TLS are not already active on the connection, data 0, v1db1

Any tips will help.
