UNIX look and feel z/OS Network File System Guide and Reference SC23-6883-00 |
|
Using the z/OS NFS with z/OS UNIX managed files provides UNIX
client users with a transparent view of their data. The file attributes
are maintained in the same way as is found on any UNIX system.
To access z/OS UNIX
files, it is necessary to be defined to RACF® as
an z/OS UNIX user. Some installations might prefer to provide users
with unrestricted access to their z/OS UNIX data by specifying security(none) or security(exports) in
the site attributes. With this setting, the client's user ID and
group ID credentials are used for all file access authentication,
and there is no requirement for the user to be defined to RACF or
to perform the mvslogin command.
Note: For the security(none) and security(exports) options,
the UID of the root (UID=0 from the workstation) is mapped to UID
of NOBODY (UID=65534) by the z/OS NFS server. The implication is that
the z/OS NFS server will use the mapped UID of 65534 for all z/OS
UNIX file authorization checking. For example, file creation owner
UID is set to 65534 in the z/OS UNIX file attribute.
