<H3>Description.</h3>
<P>
<strong>mbpasswd</strong> is the wrapper for the <strong>passwd</strong> program
is present on all GNU/Linux systems. To use <b>passwd</b> to change the password of
another user is only allowed by <b>root</b>. The mbpasswd program overcomes this limitation.
The wrapper <b>mbpasswd</b> is run from the bbs by user <b>mbse</b> when a new
user is being registered to set his password. It can also be started from the
bbs when an existing user changes his password. If you as sysop use
<strong>mbsetup</strong> to change a users password it will be used too.
His password under Unix is then always the same as his password in the bbs program.
This is necessary for the user to be able to get his email using the pop3 protocol.<P>
You never need to run <strong>mbpasswd</strong> by hand, in fact it is protected so that
it can only be started by the bbs or mbsetup.
<P>&nbsp;<P>
<H3>Environment.</H3>
<P>
<strong>mbpasswd</strong> must be installed setuid root and setgid root, ls -la looks like this:<br>
<pre>
-rws--s--x 1 root root 6644 Jun 26 21:23 /opt/mbse/bin/mbpasswd*
</pre>
<P>&nbsp;<P>
<H3>Commands.</H3>
<P>
Not mentioned here because <b>mbpasswd</b> is only called by other programs,
running manually is not supported.
