Hello,The login window does not appear by user. Could it be due to settings in Internet Explorer, if so, which ones?Thanks in advance Sebastian

Hi Sebastian, I am not very clear with your question. What is the exact behaviour your are getting? Is it automatically logging in? If you are not getting the Login Window, and the browser is automatically logging on to the SharePoint site, then it indicates that the credentials are already saved in your browser setting. To login with a different user, click on "Welcome UserName" link on Top Right side of your SharePoint Site and then select "Sign in as Different User". Hope this helps.
