SharePoint keeps prompting for credentials

One of the clients had an unusual problem accessing SharePoint. When SharePoint was accessed using Internet Explorer, user kept getting prompted for credentials. At the same time, user was able to access SharePoint using Firefox or Chrome without a problem. Weird, right? Your credentials should let you in (or not) no matter which browser you're using. Google/Bing searching did not help…

A solution to the problem ended up nothing to do with SharePoint. In the end, the problem was caused by a simple fact that the Active Directory user had "User Must Change Password at Next Logon" option turned. And, only Internet Explorer picked up on that. Once we have removed the "User Must Change Password at Next Logon", everything for back to normal. Another problem solved.

I still wonder though why did Firefox and Chrome ignored the fact that user need to change his/her password and Internet Explorer was the only browser that picked up on that. Any thoughts?
