In this assessment, Research Director Mark Diodati evaluates the abilities of off-the-shelf directory services and federation technologies that solve the increasingly prevalent provisioning and authentication challenges for cloud-based applications. Product classes evaluated include virtual directories, synchronization servers, federation products, and cloud identity management products. Use cases include provisioning and authentication to SaaS applications, the use of a cloud-based identity store, hosted applications that require Windows Kerberos authentication, and mashup of on-premises and cloud identity data. Diodati also analyzes future requirements, including increased federation token types and deeper directory services integration with Extensible Access Control Markup Language (XACML).
