Strange issue with IE,
If I go to Reverse Authentication /OWA/ I can authenticate with Firefox, but not with IE.
With IE I can authenticate only at server.com/ , so I can authenticate only at root sitepath “/”, while in FireFox I can authenticate with /, /owa/, /OWA/, /owa, /OWA so why I cannot authenticate with IE.
When authenticating with IE at /OWA/, Sophos UTM does not pass credentials to OWA. So problem is between IE and Sophos UTM.
