USERPASSWD(1) General Commands Manual USERPASSWD(1)NAME
userpasswd - A graphical tool to allow users to change their passwords.
SYNOPSIS
userpasswd [ options ]
DESCRIPTION
userpasswd is a graphical tool to allow users to easily change their passwords. Aside from being a nice GUI frontend, this program does
the right thing when the pam configuration has changed.
OPTIONS
This program has no command line options of its own, but it does take the standard X program options like -display and such. See the X(1)
man page for some of the common options.
SEE ALSO userhelper(8)BUGS
No known bugs, but compatibility with bizarre changes in the pam configuration have not been tested aggressively. If you have a non-stan-
dard pam configuration, I'd be interested to hear whether it worked and what kind of configuration you have.

userhelper - A helper interface to pam.
SYNOPSIS
userhelper [ -t ] [ -w prog args ] [ -c ] [ -f full-name ] [ -o office ] [ -p office-phone ] [ -h home-phone ] [ -s shell ] [ username ]
DESCRIPTION
NOTE this program is NOT intended to be run interactively. If you want to change this information on the command line use passwd(1),
chfn(1), or chsh(1).
This program provides a basic interface to change a user's password, gecos information, and shell. The main differnce between this program
and its traditional equivilents is that prompts are written to standard out to make it easy for a GUI wrapper to interface to it as a child
process.
The output is in the form of:
<number> <string>
Where the number is the type of prompt returned from pamlib, and the string is the prompt to give the user.
The prompt numbers are as follows:
1 Prompt with visible input.
2 Prompt with invisible input.
3 Suggested answer for the current prompt.
4 Informational message.
5 Error message.
6 Count of messages sent in this block so far.
7 The name of the service being used.
8 Whether or not the command will be executed as the user if authentication fails.
9 The name of the user being authenticated.
OPTIONS -t Use text mode authentication instead of the numbered message types just described; only used with -w.
-w Specify a program name to be run and arguments to be passed to it. userhelper will look in the file /etc/security/console.apps/pro-
gramname for the name of a user to authenticate, the path of the binary to be run, and other settings described below. userhelper
will then attempt to authenticate the user using PAM, specifying programname as the PAM service name. If authentication succeeds,
the binary will be run with superuser privileges. If the configuration file specifies that PAM session management should be per-
formed, userhelper will also open a PAM session before starting the program, and close the session when the program terminates. If
authentication fails, userhelper can be configured run the program with the user's privileges instead.
-c Change the current user's password. Note that this option cannot be used with any of the other options. This is due to the limita-
tion in the interface to pamlib.
-f Specify a new Full Name.
-o Specify a new Office.
-p Specify a new Office Phone.
-h Specify a new Home Phone.
-s Specify a new shell.
VARIABLES
USER The name of the user userhelper should attempt to authenticate the invoking user as. Typically this is root. The special value
<user> (which is also the default) indicates that userhelper should authenticate the invoking user.
PROGRAM
The name of the binary to execute if authentication succeeds. This should always be specified as an absolute path. If not speci-
fied, userhelper will attempt to run /sbin/programname first, and failing that, it will attempt to run /usr/sbin/programname.
SESSION
Specifies whether or not userhelper should perform PAM session management when running the program. Typically this is needed if the
PAM configuration uses a module such as pam_xauth.so to forward X11 authentication tokens for use by the program. Valid values are
yes and no, with the default being no.
RETRY Specifies the number of times userhelper should attempt to authenticate the user if the initial attempt fails. The default value is
2, which causes userhelper to attempt to authenticate the user a total of 3 times.
FALLBACK
Specifies whether or not the specified binary should be run with the invoking user's privileges if authentication fails. This
option is useful for running applications which gain additional abilities when run with superuser privileges, but which are still
useful when run without them.
NOXOPTION
The name of an option which, if passed to userhelper as an argument for the program it will run, will cause userhelper to behave as
if the -t flag had been passed to it.
GUI Specifies whether or not userhelper should use consolehelper to present graphical dialog boxes when prompting the user for informa-
tion. This is the inverse of the -t option. Valid values are yes and no, with the default being yes.
BANNER Specifies specific text which userhelper should present to the user when userhelper prompts for information. The default is a
generic message based on the PAM service name.
BANNER_DOMAIN
Specifies the text domain in which translations of the banner are stored. This setting is deprecated in favor of the DOMAIN set-
ting.
DOMAIN Specifies the text domain in which translations of strings are stored. If this setting is specified, it overrides any setting for
BANNER_DOMAIN which may also be set.
STARTUP_NOTIFICATION_NAME
Specifies the startup notification name used for startup notification.
STARTUP_NOTIFICATION_DESCRIPTION
Specifies the startup notification name used for startup notification.
STARTUP_NOTIFICATION_WORKSPACE
Specifies the startup notification workspace used for startup notification.
STARTUP_NOTIFICATION_WMCLASS
Specifies the startup notification binary wmclass used for startup notification.
STARTUP_NOTIFICATION_BINARY_NAME
Specifies the startup notification binary name used for startup notification.
STARTUP_NOTIFICATION_ICON_NAME
Specifies the startup notification icon name used for startup notification.
EXIT STATUS
A non-zero exit status indicates an error occured. Those errors are:
1 The authentication passwords was incorrect.
2 One or more of the GECOS fields is invalid. This occurs when there is a colon supplied in one of the fields.
3 Password resetting error.
4 Some system files are locked.
5 User unknown.
6 Insufficent rights.
7 Invalid call to this program.
8 The shell provided is not valid (i.e., does not exist in /etc/shells).
9 Ran out of memory.
10 Could not find the program.
11 exec failed even though program exists.
12 the user canceled the operation.
255 Unknown error.
FILES
/etc/passwd The gecos and shell information is stored in this file.
/etc/shells This file is checked to see if the new shell supplied is valid.
/etc/security/console.apps/prog
This file contains the values which will be used for the variables when userhelper is used with the -w flag.
/etc/pam.d/prog This file contains the PAM configuration used when userhelper is used with the -w flag.
