Thank you for your input, Nick. I see what you mean about using a full example; not yet understanding how modules work, it didn’t occur to me that cfg would be getting initialized somewhere else. My c programming skills are also rudimentary.
Regarding mod_auth_form, I am using Apache 2.2. I tried just loading a 2.4 module, but I get errors. If I knew more about Apache and how modules work, I could probably understand why I am getting the errors. Hence, the road I am on, as I find it helpful to learn this stuff anyway. (I am on Ubuntu 10.04, and there is no official package for Apache 2.4 yet available, and being a nominal linux user I would rather stick with the mainstream)
Thanks for the help :-)
