The diversity of service providers reflects the highly distributed, cross-national organisational infrastructure of biodiversity institutions and collections in general Result is a problem of identity management system administrators have to register users and maintain several access control lists for each service individually users have to remember a variety of login/password combinations to access all these different services Need for a comfortable single sign-on (SSO) solution reflecting the specifics of biodiversity infrastructures Why Community Single Sign-On ? Source: Join the federation as IdP and/or SP Identity Provider (IdP) is responsible for an organisation's secure user login and attribute delivery to SPs integration of existing identity management solutions data privacy management for user attributes Service Provider (SP) provides cross-organisational access to EDIT web resources for federated users based on individual access control policies for resources Support and demo installations available dedicated server and hosted web space environments Integration of Drupal, Spring, Trac, etc. Looking for further application scenarios Information flow of the CSSO login procedure Typical SAML-based federation infrastructure
