General password authentication using DBI-capable databases. Currently supports
MySQL and SQLite databases. The default is to use a SQLite database to store
and access user information.
This module is not an authentication protocol. For that see something such as
Authen::AuthenDBI.
SYNOPSIS
use Authen::Users;
my $authen = new Athen::Users(dbtype => 'SQLite', dbname => 'mydbname');
my $a_ok = $authen->authenticate($group, $user, $password);
