NAME¶
checkapoppw - checks APOP password against the file
~/Maildir/.password
SYNOPSIS¶
checkapoppw prog
DESCRIPTION¶
checkapoppw 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 \0, a
password terminated by \0, a timestamp terminated by \0, and possibly more
data. There are no other restrictions on the form of the login name, password,
and timestamp.
If the password is unacceptable,
checkapoppw exits 1. If
checkapoppw is misused, it may instead exit 2. If there is a temporary
problem checking the password,
checkapoppw exits 111.
If the password is acceptable,
checkapoppw runs
prog.
prog consists of one or more arguments.
There are other tools that offer the same interface as
checkapoppw
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¶
checkapoppw checks the APOP password against the content of the file
Maildir/.password (not encrypted) 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,
checkapoppw sets up
$USER,
$HOME,
$SHELL, its supplementary groups, its gid, its uid, and
its working directory.
