On SQL Server 2012 I've successfully configured FILESTREAMs and created a FileTable table. I am able to access the FileTable via the UNC path (\\server\share\tabledirectory...
). However, I'm stumped as far as how to grant permission so that other Windows users can remotely access it. I've tried granting select/insert/update/delete permission to the Windows user accounts to the FileTable table:
GRANT SELECT, DELETE, UPDATE, INSERT on TableName to [DOMAIN\joeuser]
...but that had no effect.
