<para>This global parameter determines if the tdb internals of Samba can
depend on mmap working correctly on the running system. Samba requires a coherent
- mmap/read-write system memory cache. Currently only HPUX does not have such a
- coherent cache, and so this parameter is set to <constant>no</constant> by
- default on HPUX. On all other systems this parameter should be left alone. This
+ mmap/read-write system memory cache. Currently only OpenBSD and HPUX do not have such a
+ coherent cache, and on those platforms this paramter is overridden internally
+ to be effeceively <constant>no</constant>. On all systems this parameter should be left alone. This
parameter is provided to help the Samba developers track down problems with
the tdb internal code.
