Comment 4 for bug 1393206

The policy in question is shipped in the lightdm profile, but the reporter did not mention this as a problem with the guest session specifically. I would be surprised if this ever worked in the guest session.

luca, are you trying to access the SD card from the guest session or from a normal login session? If the guest session, are you saying this used to work before in the guest session on 14.04?
