Apache basic auth access log

[dstubked]

Hi guys, i got a server that uses basic authentication on the apache web server. The basic .htaccess and .htpasswd files. How can i dig up information about who accessed password protected sites? Like in which log file can i see who visited which dir that is password protected and which user authenticated successfully?
Thanks in advanced. This is urgent. Really appreciate any help i can get now!

apache usually has an access_log and an error_log, start looking there. they are located in /var/log/apache
