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 an ordinary user is logged in the bbs. The program is called when a new user logs in the bbs or when an existing user changes his password. 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 only members of group <b>bbs</b> are allowed to use it. <P> <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> <P> <H3>Commands.</H3> <P> <code><strong>mbpasswd</strong> [-opt] [username] [password]</code> for example:<br> <pre> mbpasswd -f michiel secret </pre> Valid options are <strong>-f</strong> (forced), this will also change locked passwords, this has only effect if your system uses shadow passwords. If you use <strong>-n</strong> as option, locked passwords cannot be changed. For a new user the <b>-f</b> option is used by <b>mbsebbs</b>, when a user changes his own password the <b>-n</b> option is used. <P> <A HREF="index.htm"><IMG SRC="../images/larrow.gif" ALT="Index" Border="0" width="40" height="30"> Back to index</A> <A HREF="../index.htm"><IMG SRC="../images/b_arrow.gif" ALT="Main" Border="0" width="33" height="35"> Back to Main index</A> </BLOCKQUOTE> </BODY> </HTML>
