before we could browse through all sites without the need to enter name and
password for documents which are stored in libraries.
But now, I assume that since we have changed from http to https and redirect every http request to https, Sharepoint is asking
for username and password for each document we want to open, especially MS Office
document are affected by this. After selecting one document, I can chose to open as read-only or for editing, word starts and in the front I have to enter username and password.
It seems that PDF's are not affected by this for example.
Maybe it is caused by our AAM settings or is it any IIS setting?!
