To add to Joshua's comments about the ordering of directives:

Are you trying to "nest" authentication realms? That is, the user requests /apw5 and gets
one login prompt, then he requests /apw5/rme and gets a second prompt?

If so, that certainly won't work with basic authentication and I don't think it is even possible
in HTTP 1.1. I understand that you written your own auth module to handle the logins but I'm
guessing it's just handling the authorization [test: what is sending the 401 response to an
unauthenticated request?]

The HTTP 1.1 protocol assumes a single layer of authentication and there is no syntax for
expressing nested authentication realms. Even if you implemented it somehow in your handler,
the problem would then be in the browser implementation - if you assign an authentication
realm to /apw5, the browser will send credentials for every subsequent request under this
(ie, including /apw5/rme). So even if your handler sends back a 401 for /apw5/rme, the browser
will not know what to do (it sent credentials - why doesn't it work?). The results will be
unpredicatable and browser-dependent.
