Since the upgrade to ZCS 7 the browsers IE, Firefox and Opera ask for username and password. If you enter them you have to enter them again at the Zimbra login page. As I work with Safari I have not seen this behavior because everything is ok. My users are a little confused.
I think this has to do with SSO. Any idea how i could solve this strange behaviour?
