Comment (by MadtownLems):

 > To clarify, are you manually setting the PHP_AUTH_USER variable in your
 site?

 I apologize in advance for not being an expert in this area, and I'll do
 the best to explain.

 Our WordPress installation itself isn't specifically doing anything with
 PHP_AUTH_USER.  Rather, our webserver is a Shibboleth Service Provider and
 interacts with our University's Identity Provider to authenticate users.
 (Our WordPress installation then takes that data and uses it to associate
 the person with a WordPress user account.)

 I have confirmed that PHP_AUTH_USER gets set whenever I try to visit a
 protected directory that is not related to WordPress at all.

 I have no idea how common Shibboleth is, so here is a link for reference
 in case it's helpful:

 Always happy to answer any more questions, help look into this more, or
 test things!
