DESCRIPTION
The pts membership command lists the groups to which each user or machine specified by the -nameorid
argument belongs, or lists the users and machines that belong to each group specified by the -nameorid
argument.
It is not possible to list the members of the system:anyuser or system:authuser groups, and they do not
appear in the list of groups to which a user belongs.
To add users or machine to groups, use the pts adduser command; to remove them, use the pts removeuser
command.
OPTIONS
-nameorid <user or group name or id>+
Specifies the name or AFS UID of each user entry, the IP address (complete or wildcard-style) or AFS
UID of each machine entry, or the name or AFS GID of each group, for which to list group membership.
It is acceptable to mix users, machines, and groups on the same command line, as well as names and
IDs. Precede the GID of each group with a hyphen to indicate that it is negative.
-supergroups
List the groups to which each group specified by the -nameorid argument belongs, in addition to user
and machine members. Group membership may be nested when ptserver is compiled with the SUPERGROUPS
option enabled.
-expandgroups
Instead of listing only the groups in which the user or machine is a direct member, list every group
in which the user or machine belongs, including membership due to nested groups, for each user or
machine specified by the -nameorid argument.
Instead of listing groups which are members of a group, list every user and machine which is a member
of a group, including the users and machines which are members due to nested groups, for each group
specified by the -nameorid argument.
Group membership may be nested when ptserver is compiled with the SUPERGROUPS option enabled.
-cell <cell name>
Names the cell in which to run the command. For more details, see pts(1).
-force
Enables the command to continue executing as far as possible when errors or other problems occur,
rather than halting execution at the first error.
-help
Prints the online help for this command. All other valid options are ignored.
-localauth
Constructs a server ticket using a key from the local /etc/openafs/server/KeyFile file. Do not
combine this flag with the -cell or -noauth options. For more details, see pts(1).
-noauth
Assigns the unprivileged identity anonymous to the issuer. For more details, see pts(1).
OUTPUT
For each user and machine, the output begins with the following header line, followed by a list of the
groups to which the user or machine belongs:
Groups <name> (id: <AFS UID>) is a member of:
For each group, the output begins with the following header line, followed by a list of the users and
machines who belong to the group:
Members of <group_name> (id: <AFS GID>) are:
EXAMPLES
The following example lists the groups to which the user "pat" belongs and the members of the group
"smith:friends". Note that third privacy flag for the "pat" entry was changed from the default hyphen to
enable a non-administrative user to obtain this listing.
% pts membership pat smith:friends
Groups pat (id: 1144) is a member of:
smith:friends
staff
johnson:project-team
Members of smith:friends (id: -562) are:
pat
terry
jones
richard
thompson
The following example shows how to list the groups to which nested groups belong. In this example the
group "executives" is a member of the group "management" and the group "management" is a member of the
group "staff". The group "management" is called a supergroup of the group "executives" and the group
"staff" is called a supergroup of the group "management".
% pts membership executives
Members of executives (id: -208) are:
jane
% pts membership executives -supergroups
Members of executives (id: -208) are:
jane
Groups executives (id: -208) is a member of:
management
% pts membership management -supergroups
Members of management (id: -207) are:
executives
mary
sarah
carol
Groups management (id: -207) is a member of:
staff
% pts membership staff -supergroups
Members of staff (id: -206) are:
sales
marketing
engineering
management
Groups staff (id: -206) is a member of:
The following example shows how to find all the users which belong to a group, including users of nested
groups. In this example, the user "jane" is listed as an expanded member of the group "management"
instead of the group "executives".
% pts membership management -expandgroups
Expanded Members of management (id: -207) are:
jane
mary
sarah
carol
The following example shows how to find all the groups a user is a member of, including membership due to
nested groups. In this example the user "jane" is a direct member of the group "executives". The
"-expandgroups" flag shows all the groups to which "jane" has membership status.
% pts membership jane
Groups jane (id: 7) is a member of:
executives
% pts membership jane -expandgroups
Expanded Groups jane (id: 7) is a member of:
staff
management
executives
PRIVILEGE REQUIRED
Members of the system:ptsviewers and system:administrators groups can always use this command in any of
its variations. Additionally, a user can always list the groups to which they belong, and the owner of a
group can always list the members of the group.
Additional privileges may be granted by the setting of the third privacy flag in the Protection Database
entry of each user or group indicated by the -nameorid argument (use the pts examine command to display
the flags):
• If it is a hyphen, the default permissions described above apply.
• If it is lowercase "m" and the -nameorid argument specifies a group, then members of that group can
also list the other members. A privacy flag of "m" only changes the permissions when set for a
group. Setting this flag for a user or a machine has no effect.
• If it is uppercase "M", anyone who can access the cell's database server machines can list the
membership of the group or the groups to which that user or machine belongs, depending on what type
of entry the flag is set on.
