PASSWD(4)                DOMAIN/IX 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, it
     includes no passwords at all.

     Each field within a user's entry is separated from the next
     by a colon.  Each user is separated from the next by a new-
     line.  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.

     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 the
     DOMAIN/IX Administrator's Reference for System V, then
     update the password 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 completed.

EXAMPLE
     The line below is a prototypical record in /etc/passwd.

       robinson::uuuu:gg:Sheryl &, xxxxxxxx.xxxxxxxx://home/dir:/bin/csh

     This example shows the /etc/passwd entry for user "Sheryl
     Robinson." It includes her log-in name, a null field, her
     user and group ID numbers, her full name and uid (separated
     by a comma), home directory, and a shell field that speci-
     fies the C Shell.  (If you include an ampersand in the full
     name field, it will be expanded into the logname.  This

     labor-saving feature is, of course, only useful where some-
     one logs in with some portion of their full name.) 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.
