### Summary The University of Edinburgh, https://idp.ed.ac.uk/shibboleth. The first login page shows only a username field, and there's a continue button which reveals a password field. It's not a standard username/password page but it is working. It integrates with Cosign. ### What is the current *bug* behavior? ECCS return "Invalid Login Form". ### What is the expected *correct* behavior? ECCS should report "Unable to check". ### Relevant logs and/or screenshots See the ECCS page source for https://idp.ed.ac.uk/shibboleth ### Possible fixes No hint.
