It seems that Kerberos sessions are not renewed automatically and we need to relogin at least daily if not multiple times a day.
I am used 4-5 jenkins servers and multiple browsers and being downgraded to anonymous is a really PITA which I wish I could avoid.
Is not a very big deal to click again the login button but it would be much better if we would not have to do this so often. If I would have to do it every week it would ok, but not multiple times per day.
Imagine Google Auth, I think last time I had to login to google was few months ago, why do I need to do it more often on Jenkins?
