Hi all,

I have a standard website (one webapplication and one site collection) with some custom pages and webparts.

The issue I'm having is that when I try to switch users, using the "Sign In As a Different User" and entering new credentials (even for another site collection admin account), IE tries the account three times, and then it presents a 401 Access Denied screen.

After that, if I erase all the stuff of access denied page from the browser's url, I'm logged as the new account I just had entered and was not accepted.

After researching for a while on google, I found a KB ( http://support.microsoft.com/kb/970814 ) that might relate, but just tested here and it didn't work at all.

The modified method suggested by the KB is the following:

function LoginAsAnother(url, bUseSource) {

document.cookie="loginAsDifferentAttemptCount=0"; if (bUseSource=="1") { GoToPage(url); } else { //var ch=url.indexOf("?") >=0 ? "&" : "?"; //url+=ch+"Source="+escapeProperly(window.location.href); //STSNavigate(url); document.execCommand("ClearAuthenticationCache"); } }

But after making this change, it no longer asks for a new credential.

Any ideas?
