    NIS and NIS + (originally called Yellow Pages) are directory services (but not database) developed by Sun Microsystems, which are mostly used in UNIX environments.
    NIS +uses a hierarchical namespace. It is based on Secure RPC (see Remote Procedure Calls).
    NIS+ is designed to operate in three security levels.
    In level 0, the NIS+ server (rpc.nisd) performs no authentication to determine the legitimacy of incoming requests.
