principal’s primary name and all aliases.
group_uid A UNIX ID that identifies the group to which to apply the
overrides if neither principal_name nor principal_uid are
specified. The overrides are applied to all accounts for all
principals that are members of the identified group.
The principal_name field always acts as the keyfield and cannot be overridden. If you
enter principal_name, it identifies the specific account to be overridden. The
principal_uid or the group_uid field can act as the keyfield or they can act as override
fields. Only one of the possible keyfields is used as a key for any one entry; the others (if
entered) are used as override fields. The principal_name field takes precedence,
followed by principal_uid, and finally group_uid.
For example, if you enter principal_uid and do not enter principal_name, principal_uid
is used as the keyfield. If you enter principal_uid and principal_name, principal_name
is used as the keyfield and principal_uid is used as an override field.
If you enter the group_uid field and do not enter any other keyfields (principal_name or
principal_uid), group_uid is used as the keyfield, and the overrides apply to the accounts
of all members of the group. If you enter principal_name and group_uid,
principal_name is used as the keyfield, and the group affiliation of the named principal is
overridden by the group that is identified by the group UNIX ID.
36.2.5 Leaving passwd_override File Fields Blank
If you do not want to override an item in the passwd_override file, leave its field blank,
separating each blank field with a : (colon). You must enter one of the keyfields,
however, to identify the principal or group for which you are creating overrides. For
example, an entry to override the home directory for the account identified by mozart
looks like this:
mozart:::::/aria/wolfgang:
You must enter the colons that are associated with any blank trailing fields. In the
preceding example, a colon is required for the shell field, which is the remaining field
after the home directory field.
36.2.6 Specifying Passwords for a Specific Machine
Manually edit the password entry in the passwd_override file on the local machine to
create an entry in the override file to override passwords on the local machine. The
password that you enter must be encrypted, but you can copy the encrypted password
from the /etc/passwd file or you can write a program that generates encrypted passwords.
