hmmm. ok, lemme think on that. in general, I don't think there are
many mod_perl modules out there that re-implement default Apache
functionality, so it was never my intent to redo mod_digest in Perl.
also, all of the other Apache::Auth* modules seem to be specific
authentication schemes (Raduis, SMB, DBI, etc). what I was trying to do
was create a way for people to be able to do the same thing for Digest
auth, since there is no way now. hence the API designation - I'm really
just extending the mod_perl API proper here...

yucko. personally I hate action-at-a-distance behaviors.

I'll look more closely at this tomorrow, but I don't expect that would
ever work, as note_digest_auth_failure() is really part of the Apache
API (stolen via XS) and needs a real request object.
try
$ make test
and see if the live tests (via Apache::Test) work.
(a good time to check out the httpd-test project, no? :)

hmm. I'll take a look. I have no problem using it from either
Apache::Test or my local installation, but I may have missed something
simple. I'm on linux, fwiw. try copying the config in
t/conf/extra.conf.in and see if that works - you may need to pre-load
the module specifically via PerlModule and not a use in startup.pl...

I have no idea on either count - I'm trusting ExtUtils::MakeMaker
entirely here, which is really a pot of black magic.
anyway, as I said, I'll look more into it tomorrow.
thanks for the feedback, though. much appreciated :)
