From what I understand, there are some issues with SharePoint when using their new page types in creating these links. For some reason it strips the AD info off the call when clicking on it to go over to Track-It! which causes the login to hang. From what I understand, Sharepoint has a page type called the Classic page, which does not do this and allows it to work properly. There is also a way to link to the URL below the language selector I believe so that you are linking straight to the auto login itself and once the language is selected the first time, it shouldn't prompt again. The link should look something like this -
http: //servername/ Track-It/SelfService/Login/?showErrors=true
