NAME [Toc] [Back]
nisgrpadm - NIS+ group administration command
SYNOPSIS [Toc] [Back]
nisgrpadm -a| -r| -t ] [ -s ] group principal...
nisgrpadm -c| -d| -l [ -M ] [ -s ] group
DESCRIPTION [Toc] [Back]
nisgrpadm is used to administer NIS+ groups. This command administers
both groups and the groups' membership lists. nisgrpadm can create,
destroy, or list NIS+ groups. nisgrpadm can be used to administer a
group's membership list. It can add or delete principals to the
group, or test principals for membership in the group.
The names of NIS+ groups are syntactically similar to names of NIS+
objects but they occupy a separate namespace. A group named
"a.b.c.d." is represented by a NIS+ group object named
"a.groups_dir.b.c.d."; the functions described here all expect the
name of the group, not the name of the corresponding group object.
There are three types of group members:
+ An explicit member is just a NIS+ principal-name, for example
+ An implicit ("domain") member, written "*.west.oz.", means that all
principals in the given domain belong to this member. No other
forms of wildcarding are allowed: "wickedwitch.*.oz." is invalid,
as is "wickedwitch.west.*.". Note that principals in subdomains of
the given domain are not included.
+ A recursive ("group") member, written "@cowards.oz.", refers to
another group; all principals that belong to that group are
considered to belong here.
Any member may be made negative by prefixing it with a minus sign
('-'). A group may thus contain explicit, implicit, recursive,
negative explicit, negative implicit, and negative recursive members.
A principal is considered to belong to a group if it belongs to at
least one non-negative group member of the group and belongs to no
negative group members.
Options [Toc] [Back]
-a Add the list of NIS+ principals specified to group. The
principal name should be fully qualified.
-c Create group in the NIS+ namespace. The NIS+ group name should
be fully qualified.

-d Destroy (remove) group from the namespace.
-l List the membership list of the specified group. (See -M.)
-M Master server only. Send the lookup to the master server of the
named data. This guarantees that the most up to date information
is seen at the possible expense that the master server may be
busy. Note that the -M flag is applicable only with the -l flag.
-r Remove the list of principals specified from group. The
principal name should be fully qualified.
-s Work silently. Results are returned using the exit status of the
command. This status can be translated into a text string using
the niserror(1) command.
-t Display whether the principals specified are members in group.
Notes [Toc] [Back]
Principal names must be fully qualified, whereas groups can be
abbreviated on all operations except create.
EXAMPLES [Toc] [Back]
Create a group in the foo.com. domain:
nisgrpadm -c my_buds.foo.com.
Remove the group from the current domain:
nisgrpadm -d freds_group
Administering Members [Toc] [Back]
Add two principals, bob and betty to the group my_buds.foo.com:
nisgrpadm -a my_buds.foo.com. bob.bar.com. betty.foo.com.
Remove betty from freds_group:
nisgrpadm -r freds_group betty.foo.com.
EXTERNAL INFLUENCES [Toc] [Back]
NIS_PATH If this variable is set and the NIS+ group name is not
fully qualified, each directory specified will be
searched until the group is found (see nisdefaults(1)).
WARNINGS [Toc] [Back]

LDAP is the recommended replacement for NIS+. HP fully supports the
industry standard naming services based on LDAP.
DIAGNOSTICS [Toc] [Back]
NIS_SUCCESS On success, this command returns an exit status of
NIS_PERMISSION When you do not have the needed access right to
change the group, the command returns this error.
NIS_NOTFOUND This is returned when the group does not exist.
NIS_TRYAGAIN This error is returned when the server for the
group's domain is currently checkpointing or
otherwise in a read-only state. The command should
be retried at a later date.
NIS_MODERROR This error is returned when the group was modified
by someone else during the execution of the command.
Reissue the command and optionally recheck the
group's membership list.
