Network Shares to Sharepoint
I'll share one case similar with your requiriments at 2015/2016.
At Network Infrastructure that I job, I use the One Drive application to sync all SPO Document Library to client user folder (throw a user configuration that user defines). My job infra network contains Active Directory and Active Directory Federation Services, all AD users was synchronized with SPO. The folder of Document Library configured with granular permissions (with broken hierarchical role permission).
Note: the SPO has timeout connection, this is a securelly premisse of SPO platform; if you try configure folder mapped drive with SPO, this will kill connection after minutes.
This time, had opened several tickets at Microsoft, have a lot of conversation with SPO Engineers to solve this, the Microsoft made an update of OneDrive, then a I think this is the best way to follow.
Att,
Antonio Leonardo.
