load order dependency between mod_ldap and mod_authnz_ldap

[Stefan Fritsch]

Since the move from apr-util-ldap to ap_ldap, mod_ldap needs to be 
loaded before mod_authnz_ldap. This is somewhat annoying because the 
default httpd.conf tries to load mod_authnz_ldap first. Any ideas how 
to fix this or do we just change the order in the default httpd.conf?
