Abstract:
Cross domain authentication for web services is important when web services in one organization are
accessed from another. This paper presents the implementations of cross domain authentication in web service
environment with OpenID. OpenID integration for web-services enables authentication to web-services
regardless of the domains requester and resource provider belong to. It enables wider use of web-services
among users since OpenID has become quite popular. It also enhances the security aspect in web service
authentication, since it eliminated the use passwords for authentication between requester and resource
provider.
