[1mNAME[0m
dpns-setacl - set DPNS directory/file access control lists

[1mSYNOPSIS[0m
[1mdpns-setacl [22m[[1m-d[22m] [[1m-m[22m] [[1m-s[22m] [4macl_entries[24m [4mpath[24m...

[1mDESCRIPTION[0m
[1mdpns-setacl [22msets the Access Control List associated with a DPNS direc-
tory/file.

[4macl_entries[24m is a comma separated list of entries. Each entry has colon
separated fields: ACL type, id (uid or gid), permission. Only directo-
ries can have default ACL entries.

The entries look like:

user::perm
user:uid:perm
group::perm
group:gid:perm
mask:perm
other:perm
default:user::perm
default:user:uid:perm
default:group::perm
default:group:gid:perm
default:mask:perm
default:other:perm

The ACL type can be abbreviated to the first letter. The first "user"
entry gives the permissions granted to the owner of the file. The fol-
lowing "user" entries show the permissions granted to specific users,
they are sorted in ascending order of uid. The first "group" entry
gives the permissions granted to the group owner of the file. The fol-
lowing "group" entries show the permissions granted to specific groups,
they are sorted in ascending order of gid. The "mask" entry is the
maximum permission granted to specific users or groups. It does not
affect the "owner" and "other" permissions. The "mask" entry must be
present if there are specific "user" or "group" entries. "default"
entries associated with a directory are inherited as access ACL by the
files or sub-directories created in that directory. The [1mumask [22mis not
used. Sub-directories also inherit the default ACL as default ACL. As
soon as there is one default ACL entry, the 3 default ACL base entries
(default user, default group, default other) must be present.

The entry processing conforms to the Posix 1003.1e draft standard 17.

The effective user ID of the process must match the owner of the file
or the caller must have ADMIN privilege in the Cupv database.

[4mpath[24m specifies the DPNS pathname. If [4mpath[24m does not start with [1m/[22m, it
is prefixed by the content of the [1mDPNS_HOME [22menvironment vari-
able.

[4muid[24m can be given as the username or the corresponding numeric id.

[4mgid[24m can be given as the groupname or the corresponding numeric id.

[4mperm[24m can be expressed as a combination of characters [1mrwx- [22mor as a
value between 0 and 7.

[1mOPTIONS[0m
[1m-d [22mremove ACL entries. The "perm" field is ignored.

[1m-m [22mmodify existing ACL entries or add new entries.

[1mEXAMPLES[0m
Let's create a directory:
dpns-mkdir /dpm/dteam/test/file.log/d6
and add write permission for user bcouturi:
dpns-setacl -m u:bcouturi:rwx,m:rwx /dpm/dteam/test/file.log/d6
Let's create a directory:
dpns-mkdir /dpm/dteam/test/file.log/d7
and add default ACLs to it:
dpns-setacl -m d:u::7,d:g::7,d:o:5 /dpm/dteam/test/file.log/d7
Let's check the resulting ACLs:
dpns-getacl /dpm/dteam/test/file.log/d7
# file: /dpm/dteam/test/file.log/d7
# owner: baud
# group: c3
user::rwx
group::r-x #effective:r-x
other::r-x
default:user::rwx
default:group::rwx
default:other::r-x

Let's create a sub-directory and check the resulting ACLs:
dpns-mkdir /dpm/dteam/test/file.log/d7/d2
dpns-getacl /dpm/dteam/test/file.log/d7/d2
# file: /dpm/dteam/test/file.log/d7/d2
# owner: baud
# group: c3
user::rwx
group::rwx #effective:rwx
other::r-x
default:user::rwx
default:group::rwx
default:other::r-x

Let's create a file in the same directory and check the resulting ACLs:
dpns-touch /dpm/dteam/test/file.log/d7/f2
dpns-getacl /dpm/dteam/test/file.log/d7/f2
# file: /dpm/dteam/test/file.log/d7/f2
# owner: baud
# group: c3
user::rw-
group::rw- #effective:rw-
other::r--
