Would make sense.

You're welcome.

If you have plain passwords enabled: yes. Should be sufficient to
delete the encrypted passwords from vpasswd (empty the second field)
with 'awk') and let the users log in again. Authentication will/should
succeed, because the clear password is still there and encrypted
password will be set, as vchkpw recognizes it is empty.

This is from the top of my head, I haven't tested recently or with one
of the latest releases, so you're advised to test yourself with a
non-important account before applying the change globally.

Don't forget to run 'vmkpasswd $DOMAIN' after you modified the
'vpasswd' file(s) and before you try to login (e.g. via POP3).
Best regards

If the probability of success is not almost one, then it is damn near
