We just upgraded one of the environment from QV 10 to QV 11.
Now when the users click on the link to open the Access Point it ask for username and password everytime in order to login in access point. Its kind of annoying for the users. This was not occuring when on QV 10. They were able to login in access point without typing in userid and password.
Also try for the users where it is not happening. In IE browser setting make sure under Internet Options -> Security tab-> Internet/Local intranet->Custom Level-> Settings-> User Authentication -> Logon-> it should be Anonymous logon.
This happens to me when I use the external link. Ex:
using the internal name or internal ip of the server 10.55.2.3/qlikview the user/pass is not asked.
when using qlikserver.domain.com.br/qlikview, the user is prompted with the password.
the server is set to authenticated user. I want only the ones authenticated on our network to be able to open the reports. Anonymous seems to open to anyone. If your server is published on internet, this may be an issue.
when user access report in Ajax mode it is not asking for any credentials where when user click on IE plugin mode qlikview Login page get appear. it happens evey time and user dont want to do that every time.
