There are two ways this can be done at the moment:
In HEAD, passwords expire every 21 days, unless the 'this account does
not expire' option is set (which is the default). By the time HEAD
becomes 3.0 there should be a sane way this can be controlled from
In Samba 2.2 you can use PAM (compile --with-pam) for this. Keep your
PAM and Samba passwords in sync with the 'unix password sync' and 'pam
password change' options, and then you can enable 'obey pam
restrictions' to get password expiry - in the same way you get it for
SSH logins, for example.
