I work for a regional ISP and have a solved a similar problem. We solved
it by:

1. Users are entered into the database first through intranet server.
The user table has a boolean flag for whether or not its been modified.
2. A Perl script on our public web server queries our database every 2
minutes (run by cron).
3. The perl script adds new users to server using adduser, then sets the
modified flag to false. It also stores the value of the crypted password
back to the database.

I then use the following function in my Auth class:

  function auth_validatelogin() {
    global $username, $password;

    if(isset($username)) {
      $this->auth["uname"]=$username; ## This provides access for
"loginform.ihtml"
    }
    
    $uid = false;
    
    $this->db->query(sprintf("select user_id, crypt_password, perms ".
                             " from %s ".
                             " where username = '%s' ",
                          $this->database_table,
                          addslashes($username)));

    if ($this->db->next_record()) {
       $uid = $this->db->f("user_id");
       $pass = $this->db->f('crypt_password');
       $crypted = crypt ($password, substr($pass, 0, 2));
       if ($crypted == $pass) {
          $this->auth["perm"] = $this->db->f("perms");
          return $uid;
       } else {
          return FALSE;
       }
    }
    return $uid;
  }
