Issues with Safari and ADFS
I'm having an issue with Safari 8.0 and Microsoft ADFS 3.0. Whenever a user is redirected to the ADFS authentication portal, the page just "hangs" and never displays the authentication form. Eventually the connection will timeout and return just a generic "Safari Can't Open the Page". If you run Chrome on the same Mac, there are no issues with ADFS, so I'm convinced it is Safari specific. I have been able to duplicate the issue both on my iMac and MacBook Air.
The topic was discussed quite heavily in this thread: https://social.msdn.microsoft.com/Forums/vstudio/en-US/af0ac0c0-fdc8-42aa-91f5-9 45a29eec333/adfs-20-web-sso-not-working-in-current-versions-of-safari-for-window s-or-ios?forum=Geneva
That thread was specific to ADFS 2.0 but it looks like the same problem still exists with Safari and ADFS 3.0. Several articles seem to point to cookie size limitations in Safari as the root cause of the issue. I can find no evidence that the cookies are greater than 4K in size. I would rather not tell users that their only option is to run Chrome.
Ideas?
