I have been having issues with TMG, so i started using windows authentication instead.
Users are noticing that on some browsers, safari (mac/iphone more specifically) isn't working. Meaning, when they try to access the site, they are prompted with authentication (this is normal), and with the correct credentials, the authentication keeps prompting.
Why is this happening? Not sure if its IIS related/ Browser related. With chrome/IE, access is fine.
Any insight we be greatly appreciated.
