When opening PDFs on a https WebDAV drive in OSX, Acrobat Pro XI (and the latest Reader DC) interrupts the file open to ask for log in credentials, warning that the credentials will be sent in plain text. I can cancel it and get the file anyway, but (a) this is extremely annoying, and (b) it is highly insecure as some other users will not recognise what is going on, try to input their credentials and then send them insecurely. I think this is a bug. Can anything be done about it?
Or if someone can tell me how to stop it that would be even better.
