Hi All,

Digging up an ancient thread because it is, once again, relevant to me.
As per Iyad's suggestion, we added a special apache conf section for the
API access which sets REMOTE_USER, and API access works, but it
introduces a whole new set of issues!

History is (now?) accessed through the API, so after switching apache
over to providing a 'default' REMOTE_USER value, I can no longer access
my histories, every attempt to switch histories generates a new "Unnamed
history".

Additionally, history issue aside, this leads us to an issue with
bioblend; while we can access and interact with the API, we cannot
download datasets through the API, those are served on separate routes,
not covered by API access. During download attempts, authentication
information is required, and BioBlend returns with a 401 Unauthorized.
Upload seems to work just fine though.

Wondering if anyone had suggestions here.

For reference:

Cheers,
Eric
