access denied

Hi, I did not see this reported anywhere.

I'm no longer able to access other user profiles on gdo since the update.

I get an access denied error.

I'm working on a D6 site that could be considered an Intranet style site for members of our ministry. It is accessible from anywhere on the Internet, but should have very little content available without logging in.

How do I best lock down the site so that people have to log in before getting information without showing an "Access Denied" page at the first page where they log in? I envision a future where blogs with some public facing content could occur so I don't want to lock out that option in solving this problem.
