UserAgent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_11_2) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/49.0.2623.87 Safari/537.36

Steps to reproduce the problem:
1. Join Windows 10 V1511 (build 10586.164) to Azure AD
2. Logon with o365 identity
3. Open EDGE or IE and open portal.office.com. You have SSO logon.
4. Try step 3 with Chrome.

What is the expected behavior?
Single-Sign-On with Office 365 without having to logon manually.

What went wrong?
Chrome does not understand EPA (Extended Protection for Authentication).

Did this work before? No 

Chrome version: 49.0.2623.87 m  Channel: stable
OS Version: Windows 10 
Flash Version: Shockwave Flash 21.0 r0

The same issue is described in this issue: https://bugs.chromium.org/p/chromium/issues/detail?id=270219
However  Issue 270219  is talking about ADFS. Windows 10 Azure SSO is new feature and i believe different from ADFS(I am not sure).

"We have something new in win 10, it's called web account manager. Third party browser does not understand this. Microsoft browsers understand this and use the credentials from there and make SSO works fine."

"You seem to be referring to the Azure AD join functionality. That is a bit different from what is generally referred to as SSO with O365, and all the steps you have tried/listed above don't apply to this scenario. Afaik, there is no way to make 3rd party browsers work with that functionality, at least not currently. Anyway, you should ask this question in the Azure AD forums here:  social.msdn.microsoft.com/.../home"
