OneMAN™ is an integrated security management system for local domains. It performs registration of users, application servers, and user roles. Registration data are stored in the security database and optionally in the X.500/LDAP directory. The system performs certification of all entities (users and servers) in a local domain, issuing them certificates, handling CRLs, and other certification functions. In combination with certificates, the system may be used to issue smart cards to users and security administrators.
