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 only members of group <b>bbs</b> are allowed to use it. User <b>mbse</b> can use this program and if you do, the password for a user are not in sync anymore. <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. This is used for new users or from the <b>mbsetup</b> program to reset users passwords.<br> If you use <strong>-n</strong> as option, locked passwords cannot be changed. This mode is used when a user changes his password from the bbs. <P> <A HREF="index.htm"><IMG SRC="../images/larrow.gif" ALT="Index" Border="0">Back to index</A> <A HREF="../index.htm"><IMG SRC="../images/b_arrow.gif" ALT="Main" Border="0">Back to Main index</A> </BLOCKQUOTE> </BODY> </HTML>
