I was over at Reading earlier in the week (at the Partners in Learning Summer Camp) and also managed to catch up with James Marshall, the Live@Edu evangelist about a few things. One of the things we spoke about was identity management and here is the latest blog post about some action which needs to be taken around SSO. If you have not seen this yet and are using Live@Edu go and have a look.

Action required: Changes to Live@edu SSO Toolkit - UK Live@edu Blog - Site Home - MSDN Blogs

If your are using Live@Edu, or looking at it as an option, I would recommend you stick the above blog in your RSS feed reader too.
