Access denied message accessing symlinked existing database in data dir

Hi guys
I'm trying to load a database that I've got stored on another drive, using the same method as I currently use with MySQL
I drop a symbolic link to the database folder of the database into my data drive, and simply access it
Under MySQL this works perfectly happily, however under MariaDB, I get an access deneied message in procmon reported trying to access the db.opts file and accessing the folder itself
It doesn't matter whether I use a junction or a symlink, both error in exactly the same way.
