First a little background of the problem I'm trying to solve.
We have implemented a learning management system using SharePoint Server 2010 for a School in Australia. The Infrastructure team of the school have downloaded the SSO Tool kit from Live@Edu and they have setup the SSO Portal and now all the students have account with Live@Edu with Mail box setup. They have followed the SSO toolkit documentation to setup the SSO Portal.
We got a request to Setup a Single Sign on from SharePoint LMS to Live@Edu. Basically students will click link in the SharePoint Portal and they should be able to access their Live@edu mail box without having to enter their user name and password again. The redirect Url to the SSO link will be something like myschool/SSOPortal/redirect.aspx.
After I login to the SharePoint Portal and click the SSO link I get the error
Url displays https://account.live.com/error.aspx?errcode=1091
You Can't Complete that task here. To continue, you need to go to your organisation's website.
Does anyone have suggestions on what the error might be?
