We have Office 365 hosted by an MSP. Included in this service is an ADFS server for SSO.
The SSO have never really worked properly, so i'm going to contact them and about it. But before I do so, I just wanted to make sure that it isn't working as intended.
When i go to
portal.office.com and type in my username+upn and click in the password field I get redirected to another login screen (see image below, its in Swedish, but you should get the jist).
After I authenticate on that screen I get into the portal.
If I logout and then in again I get don't get that login screen, which is perfect. But if i close IE, open it again and go to portal.office.com again the login prompt comes up.
Isn't the point of ADFS for it to automatically log me in using my AD credentials? In my world that login-screen should never come up. In skype for business all i have to do is type my username+upn and i get logged in for instance.
So my question is: Is what i explained above correct behaviour for a properly set up ADFS SSO, or is there something amiss in the configuration?
