Description Ralph Böhme 2018-12-04 17:27:42 UTC
Samba currently implements SMB3 Create Replay by storing file handle state with Create GUID as record key in a process private in-memory database.

This means that Create Replay is not functional, as any session reconnect will result in a new Samba process that can't access the private in-memory database of the process previously servicing the session.

To address this, we need either an additional database or store the records in the smbXsrv_global.tdb database.

I'm using a sepereate db here, I guess we should just use smbXsrv_open_global.tdb for now.
