I'm wondering how dangerous it is to allow a user on a

they take the encrypted password data and possibly

I periodically export the mysql database with the encrypted user email
passwords and run it through John the Ripper, and it finds a few every
time. So it will all depend on how good the password is.
Try it yourself with John http://www.openwall.com/passwords/unix.shtml;
it's not difficult. If you use the big wordlists available at
http://www.openwall.com/passwords/wordlists/, you will be amazed at how
many passwords you can get.
