  The rlm_dbm module is deprecated, and should not be used.

  All of the functionality is has is now available in the "files"
module.  That module was fixed in 2.0 to be very fast.  It was fixed in
2.1 to support dynamic reloads.  It has been tested with 100,000 entries
in the "users" file, and is sufficiently fast for most purposes.
