History reported problem authenticating at http://web.uvic.ca/history/intranet/ . After an hour of testing, I reported to Joe Sparrow, who gave me the following advice, which worked:

The Basic Auth provider on web.uvic.ca is now LDAP. If you want to use an .htaccess and .htpasswd file you will need to put

AuthBasicProvider file

into your .htaccess file, probably before the rest of your access based commands.

I'll look at the english dept's graduate application review site (which uses a similar htaccess setup) and make necessary modifications.
