Well, this thread got a bit lost discussing other issues:
So, any comments on the usefulness of this patch?

I'm undecided myself, when I saw that I can easily lock everyone out
with this (however, that's usually the case with other pam modules).

With this option:
- Non-OPIE logins are only possible from trusted networks (those
in /etc/opieaccess),
- Consequently, users which do not have OPIE enabled can only log in
from trusted networks,
- Consequently, if /etc/opieaccess does not exist, users which do not
have OPIE enabled cannot log in (I see valid uses for this, anyway)
- Consequently, if no one has OPIE enabled, no one can log in (thus
optimum security is achieved).


Overall, I think this is useful.
I think I'm not the only one in this situation.

One basic reason for this is that most users on my network very rarelly
need shell access and even more rarelly they need it from outside.
Having complex passwords becomes hard to manage, as a user who logs in
once every three months will never remember he's password.
Account lockout is also not what I want.
