CGI doesn't work without Basic Authentication

I have a vexing problem with Apache on a Sun. We use three special
directories for scripts, all aliased as ScriptAliases. Recently I
disabled HTML basic authentication because we started using a company-
wide redirecting authentication instead. Now one of the ScriptAliases
no longer works! Apache delivers the CGIs as text files with an unrecognized
suffix.

The log gives no clue to how Apache decides whether to execute target
files as CGI files. I've tried dozens of alterations in httpd.conf
in vain. How can I investigate this problem?
