passwd & shadow

Passwords in the shadow or master.passwd file are encrypted with a one-way
function (see the crypt(3) manpage).  The original password is not
recoverable save via brute force approaches (i.e. the `crack' package).

Freeside will use the cleartext password from the RADIUS users file, if
available, otherwise it will use the encrypted password from the shadow or
master.passwd file.  Encrypted passwords are stored encrypted.  Cleartext
passwords are encrypted when exported.

You should check the exported files before you use them!  I often find it
takes several tries and some tweaking to get a sucessful import.
