Samba-3 with LDAP backend is capable in this. I'm using it and it works.
All you have to do, is to use LDAP and set proper account policies:
$ pdbedit -P "bad lockout attempt" -C 5
(after 5 wrong password, user account will be locked out - samba sets
password hashes to ***NOPASSWORD*** and user is unable to logon).
$ pdbedit -P "min password length" -C 9
# password age 90 days
$ pdbedit -P "maximum password age" -C 7776000
Samba takes age in seconds, so 60*60*24*90, is what you need.
Remember, that the user has to change his/her password from workstation
once, then policy takes effect. Another way is to manually change users
"sambaPwdMustChange" value to "0", so user is forced to change password on
next logon. After password change, new "sambaPwdMustChange" will be set,
with timestamp 90 days forward.
$ pdbedit -P "password history" -C 3
Doesn't work. Andrew said, it isn't implemented yet. Samba doesn't store
password history... I don't know how it should be done, but it would be very
nice to have it.
