If you are running your Web site without using ATG, you can still integrate it with Self Service.

For example, you could be running your Web site on one server without ATG and then run Self Service on a different server. When users are on the non-ATG Web site, they must be able to access Self Service, so you need to be able to point at Self Service from a non-ATG Web site.

To achieve this, both of your servers must use the same data and the same user profile information.
