nisgrpadm-c [-D defaults] [-M] [-s] group
DESCRIPTION
The nisgrpadm utility 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 admin‐
ister 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 func‐
tions described here all expect the name of the group, not the name of
the corresponding group object.
There are three types of group members:
o An explicit member is just a NIS+ principal-name. For exam‐
ple: wickedwitch.west.oz.
o An implicit ("domain") member, written *.west.oz., means
that all principals in the given domain belong to this mem‐
ber. No other forms of wildcarding are allowed; wicked‐
witch.*.oz. is invalid, as is wickedwitch.west.*.. Note that
principals in subdomains of the given domain are not
included.
o 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 neg‐
ative group members.
Principal names must be fully qualified, whereas groups can be abbre‐
viated on all operations except create.
OPTIONS
The following options are supported:
-a Adds the list of NIS+ principals specified to group.
The principal name should be fully qualified.
-c Creates group in the NIS+ namespace. The NIS+ group
name should be fully qualified.
-d Destroys (removes) group from the namespace.
-D defaults When creating objects, this option specifies a different
set of defaults to be used during this operation. The
defaults string is a series of tokens separated by
colons. These tokens represent the default values to be
used for the generic object properties. All of the legal
tokens are described below.
ttl=time This token sets the default time to
live for objects that are created by
this command. The value time is spec‐
ified in the format as defined by the
nischttl(1) command. The default
value is 12 hours.
owner=ownername This token specifies that the NIS+
principal ownername should own the
created object. Normally this value
is the same as the principal who is
executing the command.
group=groupname This token specifies that the group
groupname should be the group owner
for the object that is created. The
default value is NULL.
access=rights This token specifies the set of
access rights that are to be granted
for the given object. The value
rights is specified in the format as
defined by the nischmod(1) command.
The default value is
−−−−rmcdr−−−r−−−.
-l Lists the membership list of the specified group. (See
-M option.)
-M Master server only. Sends 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 Removes the list of principals specified from group.
The principal name should be fully qualified.
-s Work silently. Results are returned using the exit sta‐
tus of the command. This status can be translated into a
text string using the niserror(1) command.
-t Displays whether the principals specified are members in
group.
EXAMPLES
Administering Groups
Example 1 Creating a group
This example shows how to create a group in the foo.com. domain:
example% nisgrpadm-c my_buds.foo.com.
Example 2 How to remove a group
This example shows how to remove the group from the current domain.
example% nisgrpadm-d freds_group
Administering Members
Example 3 Adding to the group
This example shows how one would add two principals, bob and betty,
to the group my_buds.foo.com.:
example% nisgrpadm-a my_buds.foo.com. bob.bar.com. betty.foo.com.
Example 4 How to remove a principal from the group
This example shows how to remove betty from freds_group:
example% nisgrpadm-r freds_group betty.foo.com.
ENVIRONMENT VARIABLES
NIS_DEFAULTS This variable contains a defaults string that will
override the NIS+ standard defaults.
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)).

NIS_SUCCESS On success, this command returns an exit status of 0.
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 other‐
wise 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.
NOTES
NIS+ might not be supported in future releases of the Solaris operating
system. Tools to aid the migration from NIS+ to LDAP are available in
the current Solaris release. For more information, visit
