I needed to get apache webserver to use AD accounts for authentication. I followed one of the several instructions/howtos found by searching google.

But I was getting failures on starting httpd again related to AuthBasicProvider ldap. It was missing a module to allow ldap authentication to work. The module needed is:

LoadModule auth_basic_module modules/mod_auth_basic.so

Once I added this above line to modules in httpd.conf could get apache to use windows user accounts. The mod_auth_basic.so module is already installed just not enabled. Thought it might help some in the future.
