Perun — Modern approach for user and service management

In this paper we are introducing the identity and access management system called Perun. The system provides functionality which covers management of the whole user life cycle in nowadays e-Infrastructures, from user enrolment into the e-Infrastructure to user expiration. The Perun system supports management of virtual organizations, rights delegation, group management and enrolment management for making flexible user management easy to use. In comparison to ordinary identity management systems Perun also provides service and access management. Perun is a complex tool which eases management of research communities or users and services within the organizations. Perun system is used in production on national and international level; selected real deployments are described in this paper too.
