Original commit: elastic/x-pack-elasticsearch@6349f665f5
When the active directory realm was refactored to add support for authenticating against multiple
domains, only the default authenticator respected the user_search.filter setting. This commit moves
this down to the base authenticator and also changes the UPN filter to not include sAMAccountName
in the filter.
