 Note that using the session log requires searching on the {{entryUUID}}
 attribute. Setting an eq index on this attribute will greatly benefit
 the performance of the session log on the provider.
 
+The reloadhint option is configured by the

+
+directive. This option should be set TRUE when working with releases
+newer than 2.3.11 that properly support this flag. It must be set TRUE
+when using the accesslog overlay for delta-based syncrepl replication
