root:3Km/o4Cyq84Xc:0:10:System Administrator:/:/sbin/sh

-@marketing:

+:::Guest

In this example, there are specific entries for users root and joe, in

case the Network Information System are out of order.

+ User john's password entry in the Network Information System

is incorporated without change.

+ Any subsequent entries for user bob are ignored.

+ The password field for anyone in the netgroup documentation

is disabled.

+ Users in netgroup marketing are not returned by getpwent(3C)

and thus are not allowed to log in.

+ Anyone else can log in with their usual password, shell, and

home directory, but with a pw_gecos field of Guest.

NFS Warnings

The plus (+) and minus (-) features are NFS functionality; therefore,

if NFS is not installed, they do not work. Also, these features work

only with /etc/passwd, but not with a system that has been converted

to a trusted system. When the system has been converted to a trusted

system, the encrypted passwords can be accessed only from the

protected password database, /tcb/files/auth/*/*. Any user entry in

the Network Information System database also must have an entry in the

protected password database.

The uid of -2 is reserved for remote root access by means of NFS. The

pw_name usually given to this uid is nobody. Since uids are stored as

signed values, the following define is included in <pwd.h> to match

the user nobody.

UID_NOBODY (-2)

FILES

/tcb/files/auth/*/* Protected password database used when

system is converted to trusted system.

/etc/passwd Standard password file used by HP-UX.
