GPO settings for OneDrive and Sharepoint Document Library

I want to setup a GPO on my Server 2012 to push the OneDrive Sync and sharepoint Document Library sync automatically.

I have configured the GPO on my server with the following settings:

• Allow syncing OneDrive accounts for only specific organizations (ENABLED)
• Block file downloads when users are low on disk space (ENABLED)
• Configure team site libraries to sync automatically (ENABLED and Added Library ID)
• Convert synced team site files to online-only files - (ENABLED)
• Prevent users from moving their Windows known folders to OneDrive - (DISABLED)
• Prevent users from redirecting their Windows known folders to their PC - (ENABLED)
• Prevent users from syncing libraries and folders shared from other organizations - (ENABLED)
• Prompt users to move Windows known folders to OneDrive - (ENABLED)
• Prompt users when they delete multiple OneDrive files on their local computer (ENABLED)
• Set the sync app update ring - (ENABLED with DEFERRED)
• Silently move Windows known folders to OneDrive - (ENABLED)
• Silently sign in users to the OneDrive sync app with their Windows credentials - (ENABLED)
• Specify SharePoint Server URL and organization name - (ENABLED)
• Use OneDrive Files On-Demand - (ENABLED)
• Warn users who are low on disk space - (ENABLED)

However, i don't thinks so it is working because of the following reasons:

1. When user is logging into the machine, One drive still shows not signed it. It should automatically Signed in with the Windows Credentials. However, if manually click on the OneDrive icon and type username password, than it is taking all other settings from GPO (i.e. know folders redirection and etc) except SharePoint Document Library settings.
2. SharePoint Document Library is not Showing in the Explorer automatically, it should automatically configure as soon as user logs into the machine and should be able to see the folders based on the permission given to the. If I go the SP Document library, and click on Sync manually it is working. But this should be an automatic process.

GPO is Linked with Workstation OU, where all the workstation exists.

Please tell me where am i going wrong about this.
