Here is our local, out-dated (pre-5.6) version:

The HTTPD::UserAdmin and HTTPD::GroupAdmin modules provide a consistent OO interface to these files, regardless of how they're stored. Databases may be text, dbm, Berkley DB or any database with a DBI compatible driver. HTTPD::UserAdmin supports files used by the `Basic' and `Digest' authentication schemes. Here's an example:

    use HTTPD::UserAdmin ();
    HTTPD::UserAdmin
          ->new(DB => "/foo/.htpasswd")
          ->add($username => $password);
