+                       Defines the available matching uid and gid
+                       range for which the backend is
+                       authoritative. Note that the range acts as a
+                       filter.  If algorithmically determined UID or
+                       GID fall outside the range, they are ignored
+                       and the corresponding map is discarded.  It is
+                       intended as a way to avoid accidental UID/GID
+                       overlaps between local and remotely defined
+                       IDs.
