Access the Mappings tab, select one of the mappings and click Edit. As shown in the attached screenshot, the two mapped data sets can be reconciled with a "Reconcile Now" button,
but the other related terminology all specifies Sync. The terms are not identical;
Reconciliation is a type of Synchronization, as defined here – http://openidm.forgerock.org/doc/integrators-guide/index.html#sync-types
We need to either make the terms consistent, or explain the differences, perhaps with a link to the noted section.
