# The ssh_authorized_key built-in function (in 2.7.23 at least)
# will not write an authorized_keys file for a mortal user to
# a directory they don't have write permission to, puppet attempts to
# create the file as the user specified with the user parameter and fails.
# Since ssh will refuse to use authorized_keys files not owned by the
# user, or in files/directories that allow other users to write, this
# behavior is deliberate in order to prevent typical non-working
# configurations. However, it also prevents the case of puppet, running
# as root, writing a file owned by a mortal user to a common
# authorized_keys directory such as one might specify in sshd_config with
# something like
# 'AuthorizedKeysFile /etc/ssh/authorized_keys/%u'
# So we provide a way to override the built-in and instead just install
# via a file resource. There is no additional security risk here, it's
# nothing a user can't already do by writing their own file resources,
# we still depend on the filesystem permissions to keep things safe.
