Yes, but it is over a 700 mode uid 0 and gid 0 socket file , so it is
not less secure, than accessing a root owned file based kerberos
database. Anyway kerberos is a protocol designed to solve the problem of
some secure hosts connected by an insecure network. So if your KDC
machine gets compromised anything is lost no mather if you are using
LDAP or not.
