Hi all,

An update on this topic now that I've implemented a more satisfactory
solution on how to allow anonymous users to run workflows. This problem
arose when it became apparent that the journal we want to publish our
workflow in had as explicit requirement that users not be required to
register before using the web service. Galaxy at the moment requires users
to register before allowing them to use workflows, so a solution had to be
found.

I've combined ingredients from two Galaxy wiki pages to make resolve this
issue:
http://wiki.g2.bx.psu.edu/Admin/Config/Performance/Web%20Application%20Scaling
http://wiki.g2.bx.psu.edu/Admin/Config/Apache%20Proxy

>From the scaling wiki page I've copied the setup of using a single runner
Galaxy instance and multiple web front ends; in my case I'm running two
web front ends. One of these web front ends lets Galaxy administrate users
normally. The other front end I'm proxying through Apache while using the
remote user feature, as specified on the Apache Proxy page. However, rather
than relying on an external authentication mechanism, I've instead
configured Apache to set the client's remote address as the remote user
using the following directive:
RequestHeader set REMOTE_USER '%{REMOTE_ADDR}s'

This approach allows me to run a single normal web frontend allowing for
normal registration, and another one available at a distinct subdomain
using the client's IP address as implicit stable identifier. (I'm well
aware IPs are not be stable for everyone, which is still the biggest caveat
with this approach.) I'm hoping however this will still satisfy the editors
for our publication.

My intention to share this setup with the mailinglist is twofold: on the
one hand this approach could be useful to others that have to implement the
same requirements (no mandatory registration to run a workflow), while on
the other hand my approach might unknowingly lead to problems down the
road. Should this be the case please notify me how best to resolve this.
Otherwise I'm quite happy using this approach.

Best,
Tim
