+ <para>This parameter was added in Samba 3.0.23. This is an internal tuning parameter that sets
+ the hash size of the tdb used for the open file databases. The presence of this parameter
+ allows tuning of the system for very large (thousands of concurrent users) Samba setups.
+ The default setting of this parameter should be sufficient for most normal environments.
+ It is advised not to change this parameter unless advised to by a Samba Team member.</para>
