Identity Federation and Identity Providers

Identity management is one of the fastest growing areas in the security market. Currently organizations have several identity and access right repositories - often one for each IT system/application - which creates difficulties when identities and access rights need to be managed in each system and users have separate username-password combinations in each system. More and more organizations have called on software and consultant companies to implement identity management solutions to enable centralized identity and access right management and centralized identity repositories. However centrally managed repositories do not solve the problem of cross-organizational authentication and authorization.
