Hi, I am using mixed authentication in Sharepoint - FBA & Windows auth. It works fine for FBA users but when I use Windows auth. in f.ex. in Internet Explorer and when I navigate through different objects, like sharepoint lists, settings in the list than I am often redirect to login page to authenticate again.
So it looks like cookie for Windows user in IE has very short time but in FireFox it works fine as I see.
Edit: I am using custom login page - maybe here I should do sth more, but for Firefox it works fine but not in IE.
Thanx for any info.
