where:
principal_name A keyfield that contains a principal name that identifies the
principal to whose account the override applies. Enter
principal_name to apply the override only to the account for the
principal’s primary name and not to any accounts for the
principal’s aliases.
You must enter one of the keyfields (principal_name,
principal_uid,orgroup_uid) to identify the account(s) to which
the override applies.
passwd The encrypted password. If you specify an override, the
password that you enter here is in effect for this local machine
only.
You can also specify OMIT in the passwd field to disallow login
on the local machine. The use of OMIT in conjunction with an
option to the passwd_export command prevents the inclusion of
the user in the password file created by passwd_export. (See
Section 36.2.8.)
principal_uid The principal_uid field, which contains a UNIX ID that specifies
the local identity of a principal, can function as a keyfield when
the principal_name keyfield is not entered, or as a field
containing an override when entered in conjunction with
principal_name.
Enter principal_uid and not principal_name when you want to
apply the overrides to all of a principal’s accounts, including any
accounts for the principal’s aliases. The principal_uid keyfield
is especially useful for overrides to root. For example, if root
has an alias of virtuoso, an override that is keyed by principal
name applies only when root logs in as root. An override that is
keyed by root’s principal_uid applies when root logs in as root,
as virtuoso, and under any other alias.
Enter principal_uid and principal_name to override the UNIX
ID of the named principal.
group_uid The group_uid field, which contains a group UNIX ID, can
function as a keyfield when no other keyfields are entered, or as
a field containing an override when entered in conjunction with
principal_name or principal_uid.
Enter group_uid and no other keyfield (principal_name or
principal_uid) to apply the override to all members of the group
that is identified by group_uid. In this instance, the group_uid
field functions as a keyfield, identifying the accounts to which to
apply the overrides; that is, accounts whose principal is a
member of the specified group.
Enter group_uid and principal_name to change the group of the
principal that is identified by principal_name to the group that is
identified by group_uid. The change applies only to the account
for the principal’s primary name, not to any accounts for the
