nfs4mapid(8)              BSD System Manager's Manual             nfs4mapid(8)


NAME

     nfs4mapid -- shows NFSv4 mappings from uids or gids to over the wire
     string names and string names to uids or gids.


SYNOPSIS

     nfs4mapid [-G] string name
     nfs4mapid [-G] GUID
     nfs4mapid -u uid
     nfs4mapid -g gid


DESCRIPTION

     In the first form, nfs4mapid shows translations from NFSv4 string repre-
     sentations of users, and with the -G option, groups, to the corresponding
     local uids and gids.  In the second form shows the translations from
     opendirectoy GUIDS to NFSv4 strings. The well known strings names (which
     are distinguished by a trailing `@' ), such as "OWNER@" and "GROUP@" are
     represented locally by GUIDs and may not map to uids or gids. To map
     those GUIDS to NFSv4 strings use this form. The first form can be used to
     map the well known ids to GUIDs.  nfs4mapid does this by looking at the
     trailing `@' sign. Note that NFSv4 well known names are always groups and
     are used in ACEs.  In the third form, it shows the mapping from uids to
     the NFSv4 user@domain form.  Similarly, in the last form it shows the
     mapping from gids to the NFSv4 group@domain.  nfs4mapid will also show
     the intermediate GUID translation if used. The NFSv4 domain name should
     be set with dscl(1).  See opendirectory(8) for instructions.

     -G      Map an NFSv4 string to a gid.

     -u      Map a uid to an NFSv4 user@domain string.

     -g      Map a gid to an NFSv4 group@domain string.


NOTES

     nfs4mapid uses a privileged nfs client system call to pass the transla-
     tion request down to the kernel, so results will be the same as a request
     coming from an NFSv4 server. Because of this, nfs4mapid must be run with
     root privileges.
