Shibboleth doesn't work on EZproxy test, we need to review the set-up and prod and replicate it on test. There is an entry in the campus IDP for the ezproxy-test.princeton.edu domain, but we may need to reach out to the IAM group to update something.

Shibboleth settings are the /var/local/ezproxy/shibuser.txt, /var/local/ezproxy/user.txt and in /var/local/ezproxy/config.txt files.

Try logging into shib at https://login.ezproxy-test.princeton.edu/admin to produce an error. See the *.xml files that currently get written to /var/local/ezproxy when shib login fails.
