* If an sql attribute is not contained in sql, assume that it has the same name as in dialup_admin and that
  it is a reply item. Add a comment for that in conf/sql.attrmap.
* Change the way radius attributes are read from the sql database. The change should make things somewhat
  faster. Create a reverse mapping from radius attributes to dialup_admin attributes.
* Add a configuration directive called ldap_use_http_credentials. If it is set to yes then we try to
  connect to the ldap server with the username/password given in http authentication, not those contained
  in admin.conf. That way multiple admins with different permissions on the ldap tree can work on a single
  dialup_admin.
* With the same logic we allow for multiple buttons html pages. We now create a folder html/buttons which
  by default contains a folder default. If the user logs in with http authentication then we try
  to open the file html/buttons/<username>/buttons.html.php3. If we can't we open
  html/buttons/default/buttons.html.php3. That way we can create muiltiple views of say the online users
  page based on which admin requests the page.
