I'll check again, but $c->remote_addr is supposed to not exist anymore in httpd 2.4, as 
far as I know.
Indeed :

When I modify the code as follows :

	#my $client_addr = $r->connection->client_addr;
1184:	my $client_addr = $r->connection->remote_addr;
	$remote_port = $client_addr->port;
	$remote_ip = $r->connection->client_ip;

Can't locate object method "remote_addr" via package "Apache2::Connection" at 
/home/mira/EFS/lib/AUTH/SLC.pm line 1184.\n
