allowing users to change passwords

2002-01-17 Thread martin f krafft

i need to provide a way for my users to change their password on my
machines. however, most of them are too stupid for the console. so i
played with poppassd, and it might end up being my option, but today i
had another idea. so without having given it much though, i'll ask you:

what would speak against setting the user's login shell to
/usr/bin/passwd? it's SSH2-only, and with MindTerm as a java applet, i
could even ask them to connect, login with their password, type their
password again, then specify the new one twice. that shouldn't be a
problem, right? or is it absolutely bad in terms of security?

Nothing, works just fine. It might be a bit confusing for users
though since they will have to enter their original password
twice as well.

You may wish to set the motd specifically for them and explain in 
it what they need to do.

I would also audit the passwd program carefully for security 
problems like buffer overflows, etc.

Why bother having them go through the hassle of loading an applet which
might not work ( not that Ive ever seen it not work ).

If they are using mindterm, then they are already in a browser, which
means you might as well just have them use a form via ssl to change their
password via poppassd.

yes, but did you see my recent posts on poppassd and its security
problems? i am compiling poppassd-1.8-ceti from [1] right now though. it
would be the best way. i could do that in addition to passwd...
