htpasswd Pass Protection For Specific Forums?

[FakeShemp]

Hello, is there any way to have certain forums in my vbulliten system protected by apache's htpasswd?

For example, person registers for the forums and gets access to certain part of it at domain.com/forums/ but if they go to domain.com/members/forums/ they have to enter a username and pass into the gray popup apache box to get access to even more forums.

I understand that VB3 enables this via usergroups, but that is different than what I'm looking to have done.
