Hi, this is a crosspost from the Onedrive forums as recommended by their representative.
Office 365, Windows AD and hybrid AAD via Azure AD. Passwords are synced via password hash.
Win10 Education 1803 (same applies to 1809), Server 2016 at back end. Devices are shared, all users synced to local AD and of course to AAD.
Failing to get onedrive to sign in automatically for the logged on user, despite Office applications signing in automatically to currently logged on user instantly with no issues, as do all browsers when going to login.microsoftonline.com
(or 365 email).
But Onedrive will not sign in automatically at all. I think I've got it to do it, accidentally once, but never again.
ADAL is enabled (although shouldn't be necessary any more if I understand correctly)
Onedrive is latest version (19.062)
Troubleshooting with dsregcmd the only thing that jumps out at me is under user state "WamDefaultSet" : Error. Everything else appears OK.
Group policy all appears to be OK, verified by the chap on MS support. The only things sticking out are WamDefaultSet being in error state; he doesn't believe it's related to alternate login ID or proxy, narrowing it down to authentication issue.
He's suggested I ask here for support.
I appear unable to paste copy of my dsregcmd /status output due to having links it it though :(
