PASSWD(4) DOMAIN/IX Reference Manual (SYS5) PASSWD(4)
NAME
passwd - password file
DESCRIPTION
Passwd contains, for each user account, the following infor-
mation:
log-in name
numerical user ID
numerical group ID
Full name and uid
initial working directory
program to use as shell
All fields but the last are derived from data in the network
registry by the crpasswd(1m) program. On DOMAIN systems,
/etc/passwd exists soleley to provide account information in
a form familiar to UNIX programs and users. It is not used
in verifying passwords at login time and in fact, includes
no passwords at all.
Each field within a user's entry is separated from the next
by a colon. Each user entry is separated from the next by a
newline. Since encrypted passwords are maintained in the
registry and not copied into the password file by crpasswd,
the second field is always null. If the Shell field is
null, the Bourne Shell is used by default.
We supply a program, crpasswd(1M), that builds /etc/passwd,
/etc/group, and /etc/passwd.map from information in the net-
work registry. To add a new user to the system, follow the
procedures for creating a new account described in Chapter 3
of Administering Your DOMAIN System, then update the pass-
word file by running crpasswd. Do not edit the password
file unless you need to change the ``shell'' field. If you
do change this field, run crpasswd after the change is com-
pleted.
EXAMPLE
The line below is a prototypical record in /etc/passwd.
logname::uuuu:gg:Full Name, xxxxxxxx.xxxxxxxx://home/dir:
This example shows the log-in name, null field, user ID
number, group ID number, user's full name and uid (separated
by a comma), user's home directory, and a null shell field.
The uid is a unique numeric identifier derived from the time
the account was created and the node ID of the node on which
the account was created.
