authz ldap? I need to have SSO with kerberos against a AD domain

[mujzeptu]

As the title suggests, I need help setting up the latest release of Apache to use single sign-on with kerberos for an AD domain. I need users in a AD domain to automatically authenticate in apache.

I am guessing this is done through authz_ldap, however i Have no idea how to get it working... any help you can provide is greatly appreciated!
