Shibboleth

2007-03-06

Part of the infrastructure at Newcastle moved over to the Shibboleth provided by SDSS, at least as far I can tell from the login screen.

It’s fabulous. The idea is to provide a federated login so that, at least as far as I can tell, login information is managed at a single point, and allows authorisation at multiple institutions. All of this sounds like a good thing, but they’ve actually managed to achieve the notable success of making logins harder than it was before.

In the past, I would go to a URL like http://ness.cs.ncl.ac.uk, which is our coursework system, be presented with a login screen, which would login me into the system. Nowadays, I get take to a screen like this:

The purpose of this form is to let me tell the browser to go back to the system that I asked it to go in the first place. There I get another login screen which, to make our life easier, has been nobbled so that the browsers won’t remember the logins. It also seems to be crashing a lot now, so that you have to refresh your browser to get it to work.

The help link, incidentally, at the bottom takes you to a page which tells you:

SDSS Development Federation

The SDSS Federation no longer accepts new applications to join the federation. Applications should instead be made to the UK Federation.

Help is not forthcoming.
