Adapt apache log level message on multi authentication scheme
When Authentication module is set with "Mutiple" (in my case "SSL;Slave;LDAP"), for all first ones that fail, i have a "warn" message put in apache error file, before the authentication process finishes. In this case, it will be better not have these logs at a low level ("info" or "debug") : first authentication fails are "normal" case.
Exemple 1 : I have this log, before the connection form is displayed [Thu Oct 15 15:22:50 2015] [warn] Lemonldap::NG : No certificate found (172.xxx.xxx.xxx) [Thu Oct 15 15:22:50 2015] [warn] Lemonldap::NG : Client IP not accredited for Slave module (172.xxx.xxx.xxx)
Exemple 2 : If IP is accredited for Slave module (or slaveMasterIP empty), then the message is at "error" level : [Thu Oct 15 15:25:34 2015] [warn] Lemonldap::NG : No certificate found (172.xxx.xxx.xxx) [Thu Oct 15 15:25:34 2015] [error] No header Slave-Auth-User found
Moreover, each time connection form is submitted (for example wrong password), these 2 first lines are logged.
