NAME


pts_creategroup - Creates an (empty) Protection Database group entry

SYNOPSIS


pts creategroup -name <group name>+
[-owner <owner of the group>]
[-id <id (negated) for the group>+] [-cell <cell name>]
[-noauth] [-localauth] [-force] [-help]

pts createg -na <group name>+ [-o <owner of the group>]
[-i <id (negated) for the group>+] [-c <cell name>]
[-no] [-l] [-f] [-h]

pts cg -na <group name>+ [-o <owner of the group>]
[-i <id (negated) for the group>+] [-c <cell name>]
[-no] [-l] [-f] [-h]

DESCRIPTION


The pts creategroup command creates an entry in the Protection Database for each group
specified by the -name argument. The entry records the issuer of the command as the
group's creator, and as the group's owner unless the -owner argument names an alternate
user or group as the owner.

There are two types of groups:

· regular, the names of which have two parts separated by a colon. The part before the
colon names the group's owner. Any user can create such groups.

· prefix-less, which do not have an owner prefix. Only members of the
system:administrators group can create prefix-less groups.

Creating a group lowers the issuer's group-creation quota by one. This is true even if the
-owner argument is used to assign ownership to an alternate user or group. To display a
user's group-creation quota, use the pts examine command; to set it, use the pts setfields
command.

AFS group ID (AFS GID) numbers are negative integers and by default the Protection Server
assigns a GID that is one less (more negative) than the current value of the "max group
id" counter in the Protection Database, decrementing the counter by one for each group.
Members of the system:administrators group can use the -id argument to assign specific AFS
GID numbers. If any of the specified GIDs is lower (more negative) than the current value
of the "max group id" counter, the counter is reset to that value. It is acceptable to
specify a GID greater (less negative) than the current value of the counter, but the
creation operation fails if an existing group already has it. To display or set the value
of the "max group id" counter, use the pts listmax or pts setmax command, respectively.

OUTPUT


The command generates the following string to confirm creation of each group:

group <name> has id <AFS GID>

CAUTIONS


Although using the -owner argument to designate a machine entry as a group's owner does
not generate an error, it is not recommended. The Protection Server does not extend the
usual privileges of group ownership to users logged onto the machine.

OPTIONS


-name <group name>
Specifies the name of each group to create. Provide a string of up to 63 characters,
which can include lowercase (but not uppercase) letters, numbers, and punctuation
marks. A regular name includes a single colon (":") to separate the two parts of the
name; the colon cannot appear in a prefix-less group name.

A regular group's name must have the following format:

<owner_name>:<group_name>

and the <owner_name> field must reflect the actual owner of the group, as follows:

· If the optional -owner argument is not included, the field must match the AFS
username under which the issuer is currently authenticated.

· If the -owner argument names an alternate AFS user, the field must match that AFS
username.

· If the -owner argument names another regular group, the field must match the
owning group's owner field (the part of its name before the colon). If the -owner
argument names a prefix-less group, the field must match the owning group's
complete name.

-owner <owner of the group>
Specifies a user or group as the owner for each group, rather than the issuer of the
command. Provide either an AFS username or the name of a regular or prefix-less group.
An owning group must already have at least one member. This requirement prevents
assignment of self-ownership to a group during its creation; use the pts chown command
after issuing this command, if desired.

-id <id for the group>
Specifies a negative integer AFS GID number for each group, rather than allowing the
Protection Server to assign it. Precede the integer with a hyphen ("-") to indicate
that it is negative.

If this argument is used and the -name argument names multiple new groups, it is best
to provide an equivalent number of AFS GIDs. The first GID is assigned to the first
group, the second to the second group, and so on. If there are fewer GIDs than groups,
the Protection Server assigns GIDs to the unmatched groups based on the "max group id"
counter. If there are more GIDs than groups, the excess GIDs are ignored. If any of
the GIDs is lower (more negative) than the current value of the "max group id"
counter, the counter is reset to that value.

-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).

EXAMPLES


In the following example, the user pat creates groups called "pat:friends" and
"pat:colleagues".

% pts creategroup -name pat:friends pat:colleagues

The following example shows a member of the system:administrators group creating the
prefix-less group "staff" and assigning its ownership to the system:administrators group
rather than to herself.

% pts creategroup -name staff -owner system:administrators

In the following example, the user pat creates a group called "smith:team-members", which
is allowed because the -owner argument specifies the required value ("smith").

% pts creategroup -name smith:team-members -owner smith

PRIVILEGE REQUIRED


The issuer must belong to the system:administrators group to create prefix-less groups or
include the -id argument.

To create a regular group, the issuer must

· Be authenticated. The command fails if the -noauth flag is provided.

· Have a group-creation quota greater than zero. The pts examine command displays this
quota.
