1.3.1 Web Ticket Service
The Web Ticket Service is a security token service (STS). The type of credentials that a client presents to the Web Ticket Service is described in section 3.2. The security token returned in the response is called a Web ticket.
The client presents the Web ticket as its credentials when authenticating to certain Web applications. See the individual Web application specifications for details, for example, Lync Autodiscover Web Service described in [MS-OCDISCWS] or Certificate Provisioning Service described in this document. The Web ticket can be presented in the body of the Hypertext Transfer Protocol (HTTP) message or in the HTTP header, depending on the type of Web application.
