The scripts are secured since the perl script actually checks the flag
"authnotrequired" and it takes action accordingly to redirect to the login
page if the user has not logged in.

But when you enter the URL of a document that is not a Koha perl
script, there is nothing checking that the user has logged in.

One simple but inconvenient solution is to add HTTP Basic Authentication
(Apache's mod_auth) to the directory


but this is fraught with problems, i.e.

  1. you have to duplicate the borrowers table usernames and passwords
     in a htpasswd file

  2. the user has to re-enter their login details when the browser
     pops up the Basic Authentication dialogue.

  3. the login sequence in item 2 above doesn't fit in with the usual
     work flow and look 'n' feel of Koha.

Item 1. above can be alleviated by using an Apache module called
mod_auth_mysql, of which there are several. One example that seems
recent is at


Item 2. is more complex, but there is probably a solution that involves
using mod_auth_mysql plus a cookie generation mechanism that ensures
the user is logged into Koha with a proper cookie, or session ID.

Item 3. would take more work but is prolly the best solution. Have
mod_auth_mysql redirect to the login page and remember which
document was request. The document is returned once the user logs in.

This sounds like a nifty project for Koha, the ability to add
static content that falls under the same login authentication
as the scripted areas. But a bit of work!
