Please remember... the User's Information is not setup and configured on 'virgin' computers. Thus, HKCU is not ready for the EnableADAL.reg settings in the specific registry for the User as they are signing into the workstation.
We have OneDrive setup to automatically install silently & automatically configure the User's information... below are the four registry entries exported that we pushed by GPO:
--- This one is required ---
[HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\OneDrive]
"SilentAccountConfig"=dword:00000001
--- This one is required and specific to your organization ---
[HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\OneDrive\AllowTenantList]
"8deb1d4d-d0a4-4d04-xxxx-f7076cbxxxxx"=""
--- This one is optional, it checks the disk space... currently set to 500GB ---
[HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\OneDrive\DiskSpaceCheckThresholdMB]
"8deb1d4d-d0a4-4d04-xxxx-f7076cbxxxxx"=dword:00500000
--- This one is the Most Important. It creates the OneDriveADAL in the HKCU section of the registry ---
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run]
"OneDriveADAL"="powershell.exe -NoProfile -NonInteractive -WindowStyle Hidden -Command \"& {Set-ItemProperty -Path HKCU:\\\\Software\\Microsoft\\OneDrive -Name EnableADAL -Type DWord -Value 00000001 -Force}\""
Please be aware that the exported keys are not typed exactly the same way as it is entered into the GPO Manager. This is how the Most Important key is setup in the Computer Configuration section.
Hive: HKEY_LOCAL_MACHINE
Key Path: SOFTWARE\Microsoft\Windows\CurrentVersion\Run
Value name: OneDriveADAL
Value Type: REG_SZ
Value data: powershell.exe -NoProfile -NonInteractive -WindowStyle Hidden -Command "& {Set-ItemProperty -Path HKCU:\\Software\Microsoft\OneDrive -Name EnableADAL -Type DWord -Value '00000001' -Force}"
It took sometime to get this setup for our oganization. We had been inquiring with our MS rep since September 2017... got the "Preview" in early October 2017... and had it operational by early November 2017.
I hope this helps all of you IT Enterprise Administrators!
