COURIERPASSD(8) Authentication COURIERPASSD(8)NAME
courierpassd - change passwords from across the network using the Courier authentication library
SYNOPSIS
courierpassd [-hV] [-s SERVICE] [--stderr]
courierpassd -s, --service SERVICE
courierpassd --stderr
courierpassd -h, --help
courierpassd -V, --version
DESCRIPTION
courierpassd allows users to change their passwords from remote locations using the Courier authentication library. Usernames can be up to
64 characters long while passwords can be up to 128 characters long.
courierpassd uses the poppassd protocol for obtaining authentication tokens from the network. courierpassd is intended to be run from a
super-server such as tcpserver or xinetd.
The service specified by the -s switch will depend on the particular authentication modules installed. Often 'login' will be appropriate
but other possibilities include 'imap' and 'pop3'. This value defaults to 'login'. See the Courier documentation for a further explanation
of this switch.
The minimum uid that courierpassd will attempt to change a password for can be set at compile time using the configure option --with-
minuid. courierpassd will refuse to change the password of a user whose uid is below this value. The default value is 100. This value
should never be set to 0 as this would allow root's password to be changed from a remote location.
A second configure option, --with-badpassdelay, can be used to set the delay in seconds that courierpassd sleeps after an unsuccessful
password change attempt. This feature is designed to make brute force attacks against passwords harder to perform. The default value is 3.
LOGGING
Logging is done to syslog by default or to stderr if the --stderr switch is used. courierpassd logs all password change attempts whether
they are successful or not.
courierpassd does certain checks on command line arguments so it is important to put --stderr first in the argument list if it is to be
used in order for these checks to be logged properly.
EXAMPLE CLIENT-SERVER CONVERSATION
All messages passed between server and client are text based allowing a client session to be easily mimicked with telnet. Using telnet,
changing a user's password would look like this:
Connected to localhost.localdomain (127.0.0.1).
Escape character is '^]'.
200 courierpassd 1.1.2 hello, who are you?
user <username>
200 Your password please.
pass <current password>
200 Your new password please.
newpass <new password>
200 Password changed, thank-you.

200 Bye.
