Uma resposta parece ser no faq que você vinculou , aparentemente ntfs-3g precisa setuid para fazer o que você pergunta:
chown root $(which ntfs-3g) chmod 4755 $(which ntfs-3g)
Please note that using setuid-root can result unforeseen privilege escalation and its usage is discouraged. Only the absolutely trusted users must be granted such access. Below is an example how this can be done for users in the ntfsuser group to be able to mount any NTFS volume if they have also the needed volume access rights.
addgroup ntfsuser chown root:ntfsuser $(which ntfs-3g) chmod 4750 $(which ntfs-3g) usermod -aG ntfsuser allowed-user
The setuid-root ntfs-3g driver applies the principle of least privilege during its lifetime as a safety measure.
