I have got a MyBook Live Duo for quite some time now and use private shares quite successful to limit access.
The main reason was to avoid unintentional deletion but also to hide some content.
This worked fine in my home network for several Windows and Mac devices and a WD TV having access to the NAS.
Some shares are visible to only some, most are public. Another share is not visible at all, unless the correct user/pw is presented. So far so good…
Recently I tried a Fire TV (Amazon) and installed Xbmc, and everything works fine.
Even too good: Without any deeper knowledge I choosed the option NFS at Xbmc, and all (!) shares got visible and accesible. I found some links, this would work for the public share only (maybe got this wrong), but it works fine for all shares.
The strange thing: I did not add any user information, nor any password.
Also the one mentioned private share (enabled for a specific user only, not even Admin) is visible, accessible and so on.
The “Media Streaming” feature and DLNA are completely disabled @MyBook.
As I mentioned: On Win and Mac the security seems to work, but not for Xbmc.
Anything I missed? Or a “feature” = security bug?
