When preparing for the Red Hat Certified Engineer certification examination, I came across this quote in my study notes about the sudo command.By default, the policy is maintained as a flat text file, /etc/sudoers(although other, possibly remote, backend databases are also supported).I have never heard of this piece of information until recently and a quick Google search does not turn up anything useful with regards to this.Is this particular quote accurate? If so, how do I make the appropriate changes to configure sudo to use an alternative(presumably centralized) database for its policies?
What alternative backends does sudo support and how is it configured?
linux;rhel;sudo
