On Linux you would use write your own PAM module to validate the user
against your database.

Alternatively, you could sync your database with /etc/shadow or change
/etc/nsswitch.conf to use db for shadow (password hash) information
instead of /etc/shadow

Another option would be export the database via ldap and use ldap for
authentication.
