Just to be clear, are you saying that a user with privileges to access a specific shared directory can access their share as as starting point and navigate up the directory tree to access other directories for which he/she does not have privileges?
Sorry if i wasn't clear.
There is no error or bug in the share management.
Users can only access the shares for which they have privileges.
However they can see (not access) all other shares and also Volume_1.
For instance in my workgroup when user1, with access privileges only to
Share1 opens the DNS-327 ip he gets:
IPC$
lp
Media
Share1
Share2
Volume_1
User1 can see all shares in DNS but can only access his share - Share1.
Perhaps the solution is to have a hidden share attribute so that it is possible to hide Volume_1.
Thank you
