Require password to mount external drives

[allaboutsam]

Is there a way in Lucid to require a sudo password to mount all external drives (e.g. thumb drives, USB CD/DVD drives, USB hard drives)?

Thanks,

You have to overwrite the default policykit settings. Create a .pkla file in /var/lib/polkit-1/localauthority/50-local.d/.

i.e.
/var/lib/polkit-1/localauthority/50-local.d/external.drives.pkla:

[Mounting, ejecting of external drives]
Action=org.freedesktop.udisks.filesystem-mount;org.freedesktop.udisks.drive-eject;org.freedesktop.udisks.drive-detach
ResultActive=auth_admin_keep

Check out:

man pklocalauthority
