PASSMGMT(8) Maintenance Commands and Procedures PASSMGMT(8)

NAME

passmgmt - password files management

SYNOPSIS

passmgmt -a options name


passmgmt -m options name


passmgmt -d name

DESCRIPTION

The passmgmt command updates information in the password files. This
command works with both /etc/passwd and /etc/shadow.


passmgmt -a adds an entry for user name to the password files. This
command does not create any directory for the new user and the new
login remains locked (with the string *LK* in the password field)
until the passwd(1) command is executed to set the password.


passmgmt -m modifies the entry for user name in the password files.
The name field in the /etc/shadow entry and all the fields (except
the password field) in the /etc/passwd entry can be modified by this
command. Only fields entered on the command line will be modified.


passmgmt -d deletes the entry for user name from the password files.
It will not remove any files that the user owns on the system; they
must be removed manually.


passmgmt can be used only by the super-user.

OPTIONS

-c comment
A short description of the login, enclosed in quotes.
It is limited to a maximum of 128 characters and
defaults to an empty field.


-e expire
Specify the expiration date for a login. After this
date, no user will be able to access this login. The
expire option argument is a date entered using one of
the date formats included in the template file
/etc/datemsk. See getdate(3C).


-f inactive
The maximum number of days allowed between uses of a
login ID before that ID is declared invalid. Normal
values are positive integers. A value of 0 defeats
the status.

Changing the password reactivates an account for the
inactivity period.


-g gid
GID of name. This number must range from 0 to the
maximum non-negative value for the system. The
default is 1.


-h homedir
Home directory of name. It is limited to a maximum of
256 characters and defaults to /usr/name.


-K key=value
Set a key=value pair. See user_attr(5), auth_attr(5),
and prof_attr(5). The valid key=value pairs are
defined in user_attr(5), but the "type" key is
subject to the usermod(8) and rolemod(8)
restrictions. Multiple key=value pairs may be added
with multiple -K options.


-k skel_dir
A directory that contains skeleton information (such
as .profile) that can be copied into a new user's
home directory. This directory must already exist.
The system provides the /etc/skel directory that can
be used for this purpose.


-l logname
This option changes the name to logname. It is used
only with the -m option. The total size of each login
entry is limited to a maximum of 511 bytes in each of
the password files.


-o
This option allows a UID to be non-unique. It is used
only with the -u option.


-s shell
Login shell for name. It should be the full pathname
of the program that will be executed when the user
logs in. The maximum size of shell is 256 characters.
The default is for this field to be empty and to be
interpreted as /usr/bin/sh.


-u uid
UID of the name. This number must range from 0 to the
maximum non-negative value for the system. It
defaults to the next available UID greater than 99.
Without the -o option, it enforces the uniqueness of
a UID.

EXIT STATUS

The passmgmt command exits with one of the following values:

0
Success.


1
Permission denied.


2
Invalid command syntax. Usage message of the passmgmt command is
displayed.


3
Invalid argument provided to option.


4
UID in use.


5
Inconsistent password files (for example, name is in the
/etc/passwd file and not in the /etc/shadow file, or vice
versa).


6
Unexpected failure. Password files unchanged.


7
Unexpected failure. Password file(s) missing.


8
Password file(s) busy. Try again later.


9
name does not exist (if -m or -d is specified), already exists
(if -a is specified), or logname already exists (if -m -l is
specified).

NOTES

Do not use a colon (:) or RETURN as part of an argument. It is
interpreted as a field separator in the password file. The passmgmt
command will be removed in a future release. Its functionality has
been replaced and enhanced by useradd, userdel, and usermod. These
commands are currently available.


This command only modifies password definitions in the local
/etc/passwd and /etc/shadow files. If a network nameservice is being
used to supplement the local files with additional entries, passmgmt
cannot change information supplied by the network nameservice.
