NGROUPS_EGID process’s effective gid
NGROUPS_RGID process’s real gid
NGROUPS_SGID process’s saved gid
NGROUPS_SUPP process’s supplementary groups only
NGROUPS_EGID_SUPP process’s eff gid plus supp groups
NGROUPS_RGID_SUPP process’s real gid plus supp groups
NGROUPS_SGID_SUPP process’s saved gid plus supp groups
WARNINGS
ACLs cannot be used to restrict the superuser’s access.
Most, but not all, supported utilities are able to handle ACLs correctly. However, only the fbackup(1M) and
frecover(1M) file archive utilities handle access control lists properly. When using programs (such as
archive programs ar(1), cpio(1), ftio(1), tar(1), and dump(1M)) unable to handle ACLs on files with optional
ACL entries, note the Access Control List information included on their respective reference pages, to avoid
loss of data.
DEPENDENCIES
NFS
NFS does not support ACLs on remote files. Individual manual entries specify the behavior of various
system calls, library calls, and commands under these circumstances. Be careful when transferring a
file with optional entries over a network or when manipulating a remote file because optional entries
may be silently deleted.
AUTHOR
The access control list design described here was developed by AT&T.
