The demand for secure access poses a serious challenge to computer professionals. System Administrators must balance ease of use considerations with the need to protect valuable business data and a wide range of access levels. Enterprise and datacenter management primarily includes Linux and Windows systems and users requiring shared access across all systems and access protocols, regardless of the source. Identity and access management tools must successfully handle complex user provisioning, lifecycle management, certificate-based trusts, and the ability to perform Single Sign-On across local and remote networks, services, and devices. Identity Management (IdM) in Red Hat Enterprise Linux solves these business security needs.
