checkpw
checkpw(8) System Manager's Manual checkpw(8)
NAME
checkpw - checks password against the file ~/Maildir/.password
SYNOPSIS
checkpw prog
DESCRIPTION
checkpw reads descriptor 3 through end of file and then closes descriptor 3. There must be at most 512 bytes of data before end of file.
The information supplied on descriptor 3 is a login name terminated by , a password terminated by , a timestamp terminated by , and
possibly more data. There are no other restrictions on the form of the login name, password, and timestamp.
If the password is unacceptable, checkpw exits 1. If checkpw is misused, it may instead exit 2. If there is a temporary problem checking
the password, checkpw exits 111.
If the password is acceptable, checkpw runs prog.
prog consists of one or more arguments.
Compatible tools
There are other tools that offer the same interface as checkpw
Note that these tools do not follow the getopt interface. Optional features are controlled through (1) the tool name and (2) environment
variables.
The password database
checkpw checks the password against the content of the file Maildir/.password in the user's home directory corresponding to the login name.
Maildir may be overidden through the environment variable $MAILDIR.
Process-state changes
Before invoking prog, checkpw sets up $USER, $HOME, $SHELL, its supplementary groups, its gid, its uid, and its working directory.
FILES
~/Maildir/.password
