Thanks for your reply. But as a matter of fact I have Read a whole bunch
of FM's, including "man usermod".

Unfortunately usermod does something completely different from what I want
to implement: the only limit it can set on a password is an expiry date.

What I need is a password that can be used only for the _first_ ever login
of a user. After logging in the user would be presented with a query for a
new password, which is henceforth used in the normal way (the expiries and
stuff for this are already in place and working).

I hope my question is clearer now :o)

Kind regards,
