WS-Trust is a web service specification that provides extensions to WS-Security. The "Security Token Service" component of WSO2 Carbon enables you to configure the generic STS to issue claim-based security tokens. A claim-based security token is a common way for applications to acquire and authenticate the identity information they need about users inside their organization, in other organizations, and on the Internet. This Security Token Service is capable of issuing SAML 1.1 and SAML 2.0 tokens as recommended in WS-Trust and SAML Web Service Token Profile specifications. One of the main advantages of this STS is the reduced complexity for the web service consumer.
