The new system uses the Red Hat Identity Manager (IdM) as a single integrated front-end to the Lightweight Directory Access Protocol (LDAP) and a replacement for NIS and a stand-alone Kerberos authentication service. This system allows for integration of authentication across Unix and Windows environments and across different JLab computing environments, including across firewalled networks. The decision making process, conversion steps, issues and solutions will be discussed.
