How to in http://msd开发者_开发技巧n.microsoft.com/en-us/library/bb472488.aspx add a security. For example I want to post data only users from domain: DOMAIN\User1 and DOMAIN\User2. Thanks.

You can configure the service in your link example as shown in this answer to get what you want. You then use IIS manager (if the service is hosted in IIS) to set which users (or preferably domain groups) have permission to access to your service.
