* accesses), but on a machine that was not necessarily trusted to hold the

*
* Such a configuration is, of course, insecure because anyone can make
* inbound RPCs and manipulate the database, including creating bogus
* dumps and restoring them! Additionally, in modern usage, butc is
* frequently run with -localauth to authenticate its outbound connections
* to the volservers and budb with the cell-wide key, in which case the
* cell-wide key is present and could be used to authenticate incoming
* connections as well.
*
* If -localauth is in use, create the full barrage of server security
* objects, including rxkad, so that inbound connections can be verified
* to only be made by authenticated clients. Otherwise, only the rxnull
* class is in use with a single server security object. Note that butc
* will refuse to start in this configuration unless the
* "-allow_unauthenticated" flag is provided, indicating that the operator
* has ensured that incoming connections are appropriately restricted by
* firewall configuration or network topology.
