/UID=n

    Optional. Default: -2.

    Default UID if no UID mapping exists for file access.

    Restriction: Requires OPER privilege.

    Both the NFS server and NFS client use the proxy database for
    access control. HP strongly recommends that you provide a proxy
    with a unique UID for every NFS client user.

    If you need to provide universal access to world-readable
    files, you can use the default UID to avoid creating a proxy
    for every NFS client user. You should avoid using the default
    UID if clients require additional file access; otherwise, client
    users may see unpredictable and confusing results when they try
    to create files. Refer to the HP TCP/IP Services for OpenVMS
    Management manual for a detailed discussion about using proxies,
    the default user, and security considerations.
