/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.
