Login errors not being written

When I use the wrong password on the initial login to FreePBX, the errors don’t seem to be logged anywhere. They’re not going to /var/log/httpd/error_log. I don’t see them going anywhere else either. Anybody know why this is the case and how I can get these login errors to be logged? I first noticed this issue when testing out Fail2ban and realizing it didn’t lock me out because of login errors. Thanks.

OS: CentOS 5.5
Asterisk: 1.6.2
FreePBX: 2.7
