Who says you can use "2" as an argument to SSLVerifyClient? According to it takes:

- none: no client Certificate is required at all 
- optional: the client may present a valid Certificate 
- require: the client has to present a valid Certificate 
- optional_no_ca: the client may present a valid Certificate
but it need not to be (successfully) verifiable. 

In any case, the usual rule is that directives which apply to one
directory are inherited by its subdirectories. I'd be surprised if this
were different.

How did you test this? You aren't expecting the browser to pop-up
certificate dialogue windows every time you go down a dir, are you? To
prove this is happening as you describe you'd have to access
/htdocs/test from a client WITHOUT a cert, demonstrate that you are
denied access, then change the request to /htdocs/test/subdirectory and
demonstrate that you obtain access. Can you do this?
