The System Administration Tools
Network Information System network database. A line beginning with a
plus (+) is used to incorporate entries from the Network Information
System. There are three styles of + entries:
+ Insert the entire contents of the Network Information
System password file at that point;
+name Insert the entry (if any) for name from the Network
Information System at that point
+@name Insert the entries for all members of the network
group name at that point.
If a + entry has a nonnull password, directory, gecos, or shell field,
they override what is contained in the Network Information System.
The numerical user ID and group ID fields cannot be overridden.
The passwd file can also have lines beginning with a minus (-), which
disallow entries from the Network Information System. There are two
styles of - entries:
-name Disallow any subsequent entries (if any) for name.
-@name Disallow any subsequent entries for all members of
the network group name.
WARNINGS
User ID (uid) 17 is reserved for the Pascal Language operating system.
User ID (uid) 18 is reserved for the BASIC Language operating system.
These are operating systems for Series 300 and 400 computers that can
coexist with HP-UX on the same disk. Using these uids for other
purposes may inhibit file transfer and sharing.
The login shell for the root user (uid 0) must be /sbin/sh. Other
shells such as sh, ksh, and csh are all located under the /usr
directory which may not be mounted during earlier stages of the bootup
process. Changing the login shell of the root user to a value other
than /sbin/sh may result in a non-functional system.
The information kept in the pw_gecos field may conflict with
unsupported or future uses of this field. Use of the pw_gecos field
for keeping user identification information has not been formalized
within any of the industry standards. The current use of this field
is derived from its use within the Berkeley Software Distribution.
Future standards may define this field for other purposes.
The following fields have character limitations as noted:
+ Login name field can be no longer than 8 characters;
+ Initial working directory field can be no longer than 63
characters;
+ Program field can be no longer than 44 characters.
+ Results are unpredictable if these fields are longer than the
limits specified above.
The following fields have numerical limitations as noted:
+ The user ID is an integer value between -2 and UID_MAX
inclusive.
+ The group ID is an integer value between 0 and UID_MAX
inclusive.
+ If either of these values are out of range, the getpwent(3C)
functions reset the ID value to (UID_MAX).
