I'm having a problem with my ADFS implementation :
When I attempt to connect to Office 365 (through portal.microsoftonline.com) using a federated user the browser keeps on prompting for my credentials even though I've correctly filled in the fields.
I don't have any error message in my Event Viewer
Thanks for your help !
Thanks for the feedback.
I had this problem and the cause was that the internal DNS had a CNAME instead of an A record pointing to the name of the federation service. After changing it to A, SSO started working immdiately and the 401.2 errors disappeared.
Strange I´m using a CNAME internally to point to the ADFS server and I have no problems with SSO.
I was told by Office 365 support that ADFS and IIS were "out of scope" for them...
what key did you change in registry and what brought you to that change, please ?
he added a DWORD value DisableLoopbackCheck (as data entered 1) to key HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa
