Discussed with Engineering and opening reminder ticket to review https://github.com/freenas/freenas/pull/2836 for changes seperate from the associated tickets. Specifically, confirm that
'idmap_adex','idmap_hash', 'idmap_tdb2', and 'ServiceMonitor'
are removed from the docs.
Also review this overview post: https://www.reddit.com/r/freenas/comments/bgji05/changes_to_ad_directory_service_in_freenas_113/ to see if any other changes to AD docs are needed.
