ADIbizaUX - (Active Directory Ibiza UX) Active Directory Portal extension for Ibiza portal(portal.windowsazure.com).
Active Directory Ibiza UX is a stateless UI service built on top of Ibiza SDK to be used in portal.azure.com portal to allow UX in the Ibiza portal for IAM services. It is comprised of 2 services (but which work only together for meaningful operation) - frontend (hosted by azure portal hosting service), and backend (deployed by WARM/EAP).
