The following diagrams highlight the differences between using OpenID (specifically designed as an authentication protocol) and OAuth for authorization. The communication flow in both processes is similar: (Not pictured) The user requests a resource or site login from the application. The site sees that the user is not authenticated.
The diagram from [5] (see right) highlights key additions that UMA makes to OAuth 2.0. In a typical OAuth flow: A resource owner (RO), a human who uses a client application, is redirected to an authorization server (AS) to log in and consent to the issuance of an access token.
Enables OAuth 2.0 implementations to apply Token Binding to Access Tokens, Authorization Codes, Refresh Tokens, JWT Authorization Grants, and JWT Client Authentication. This cryptographically binds these tokens to a client's Token Binding key pair, possession of which is proven on the TLS connections over which the tokens are intended to be used.
The eXtensible Access Control Markup Language (XACML) is an XML-based standard markup language for specifying access control policies. The standard, published by OASIS, defines a declarative fine-grained, attribute-based access control policy language, an architecture, and a processing model describing how to evaluate access requests according to the rules defined in policies.

Indeed, the flow outlined in the previous section is sometimes called the Lightweight Web Browser SSO Profile. Alternatively, for increased security or privacy, messages may be passed by reference . For example, an identity provider may supply a reference to a SAML assertion (called an artifact ) instead of transmitting the assertion directly ...
The Central Authentication Service (CAS) is a single sign-on protocol for the web. [1] Its purpose is to permit a user to access multiple applications while providing their credentials (such as user ID and password) only once.
The Shibboleth project was started in 2000 to facilitate the sharing of resources between organizations with incompatible authentication and authorization infrastructures. Architectural work was performed for over a year prior to any software development. After development and testing, Shibboleth IdP 1.0 was released in July 2003. [1]
