Apache authentication scheme

Apache has an authentication scheme using .htaccess and a password file to authenticate people from accessing an area of the site.

Is there anyway to set .htaccess to use the Unix password file to authenticate users.

Thanks in advance

Yes, check Apache's site for details. However, you do not want to do this!! As noted on their site, Apache does not log failed login attempts. Anyone with connectivity to your machine will be able to brute force your passwords with no reliable way for you to detect it.
