I have installed squid and dansguardian on a server somewhere in my lab and I want to implement a way for someone to bypass the block with a password. I don't want to install anything extra, I want to make this work with only dansguardians pre-installed features. Is password bypass one of them?

Kind of dated (11/15/07) but may still apply?

I have read that there are much more secure methods to do this. Many resources that are on the internet how accomplishing this are either old or very vague (not enough detail in order to understand the tutorial). I am interested in making the usernames and passwords match the htaccess file (either make the login boxes show up on the page which would be more complicated since I am a bit rusty with HTML, or you can make the htaccess login window appear when you press a link on the block page to enter username and password. when the credentials are correct it should allow you to use the website that was blocked). What I am really interested in doing is getting the usernames and passwords to match those that are on an active directory machine.

You lost me at AD. Sorry.
