Hi johncenalk,
But then, I see a security risk. Imagine my desktop is "ComputerA", and I share a folder "private" with user account "UserPrivate", defined both on my desktop and also on my laptop "ComputerB". I, when logged in as "UserPrivate" in any of those two computers, would be able to access folder "private" in "ComputerA". OK. So far, that works.
But I guess that the user account "UserPrivate" does not have to have the same password on "ComputerA" and "ComputerB". Why do I say this? Because the network and sharing options let you choose a user on your computer, regardless of its password. I don't think my computer ("ComputerA") knows whether "UserPrivate" in "ComputerB" has the same password as in "ComputerA", because otherwise it would have allowed me to choose directly that remote user. So, my theory is that it disregards passworks. You share a folder with a certain user NAME.
If that is the case, another computer, neither at my home nor mine, could also create (knowingly or accidentally) a user account named "UserPrivate", and that user would be able to access my "private" folder, and I don't want that.
I'll do some tests to check this.
Thank you.
