I've recently noticed a problem that prevents users from logging into my website when running IE8 on Vista. I think it is a security issue that prevents the authentication cookie from working. There seems to be an issue with either of these two methods:
Authentication works ok in FireFox and Google Chrome running on the same Windows Vista machine with the IE8 problem. Authentication works ok on a 2003 server computer running IE7. I'm pretty sure authentication was working previously in IE8 - maybe the issue is related to a recent hotfix?
I managed to get authentication to work in IE8 by adding my website to the "trusted sites" zone. Also, it worked ok when I disabled "Protected Mode".
Has anybody else had this problem? Also, is there a way to get this working without forcing people to make changes to their IE security settings?
