UNIX ID. If you specify both keyfields in an override entry, the group name is used as
the lookup key; subsequent fields are used as overrides.
36.2.3.3 Field Descriptions
The following list describes each entry in the file group_override:
group_name A keyfield that contains the name that identifies the group to which the
override applies.
passwd This field specifies the encrypted password. If you specify an override
in this field, the password you enter is in effect for this local machine
only.
The use of OMIT along with an option to the passwd_export
command prevents the inclusion of this group in the group file created
by the passwd_export command. This effectively disallows newgrp
commands to this group on the local machine. (See Section 36.2.3.5
for details.)
group_uid A UNIX group ID. This field can function as a keyfield when no other
keyfields are entered. It can also function as a field containing an
override when entered along with group_name. The group_uid value
specifies the local override of the group ID supplied by the network
registry server.
members This field specifies a comma-separated list of members of the group.
The contents of this field will override information in the registry when
the passwd_export command creates an /etc/group file. Note that, to
specify a null membership, as opposed to indicating that no override is
required, use a * (asterisk) for this field.
36.2.3.4 Leaving Fields Blank
If you do not want to override an item, leave its field blank, separating each blank field
with a : (colon). Note that, to override a group with a null membership list, enter an
asterisk for the members field.
36.2.3.5 Using OMIT
If you specify OMIT and issue a passwd_export command with the -x option, then the
named group will not appear in the /etc/group file produced by the passwd_export
command. Subsequent to this, users will not be able to issue a newgrp command to this
group on the local machine.
