No protocol-specific initialization is required to use this protocol. Standard SOAP bindings MUST be established between the client and server before initiating communication.
For clients running on the local machine, the standard STS server SOAP endpoint address is net.tcp://localhost/samlprotocol. For clients running on remote machines connecting to a server, the standard STS server SOAP endpoint address is https://contoso.com/adfs/services/trust/samlprotocol/proxycertificatetransport, where contoso.com represents the server domain name. Other port addresses MAY be used by implementations. <1>
