Hi,


My website is protected using Windows Authentication.


Since upgrading to MacOS I can no longer access it using Safari, other browsers such as Chrome work OK.


I receive the popup to enter my user name and password with the option to remenber the password in my keychain. If I enter the username/password, the popup disappears then reappears. I enter the username/password again and the popup disappears then reappears. This happens continuously until I cancel the popup then I get the message:


HTTP Error 401.2 - Unauthorized

You are not authorized to view this page due to invalid authentication headers.


Has anybody else experienced this issue with Safari 10 on MacOS?


Thanks,

Tony.

I just installed the 1st beta and have the exact same problem. Did a WireShark trace and it looks like Safari is never sending the NTLM authorization but instead just keeps on re-requesting the page without providing the credentials, even although it asks for them.

Thankful that I'm not the only one to catch this. We may just have to log the Radar and wait for the next build or perhaps Safari Technical Preview. The issues I saw were pretty consistent across various sites withsome sort of external SSO (WebEx, ServiceNow, Verian). For me, though, SSO (SAML or Kerberos) fails and then I get the login dialog, which I assume is NTLM, which eventually locks my AD account. This would be explained by the empty credentials.


For now, I can just use Firefox, which doesn't seem to handle SSO out of the box (I haven't really dug into this yet), but NTLM does work.

I've just checked and with the latest update, Version 4, the issue appears to be solved

This is indeed fixed in the new beta. However what is still broken when one has a share connected through Finder requiring different credentials.
