Dominique Jäggi commented on OAK-4825:
--------------------------------------
as discussed by phone with [~alexander.klimetschek], the removal and re-syncing
of group memberships upon enable/disable will not be part of the patch. it is
the client's responsibility of filtering users by disabled status instead of
having oak remove groupmembership upon which filtering previously occurred in
the requestor's application.
> Support disabling of users instead of removal in DefaultSyncHandler

> The DefaultSyncHandler by default will remove (local) users when they are no
> longer active in the external system aka no longer provided by the
> ExternalIdentityProvider. It would be useful to have an option to _disable_
> users instead of removing them completely.
> This is good for use cases that need to keep the user's data around in the
> JCR and can't just delete it. Also, we have seen cases where the user is only
> temporarily removed from the external identity system (e.g. accidentally
> removed from group that maps them to the JCR system and quickly added back),
> where a full removal can do unnecessary operations.
> (Note: There is an [option in the SyncContext
> interface|https://github.com/apache/jackrabbit-oak/blob/trunk/oak-auth-external/src/main/java/org/apache/jackrabbit/oak/spi/security/authentication/external/SyncContext.java#L38]
> to suppress purging completely, aka they won't be removed nor disabled, and
> the JMX sync commands such as
> [purgeOrphanedUsers()|https://github.com/apache/jackrabbit-oak/blob/trunk/oak-auth-external/src/main/java/org/apache/jackrabbit/oak/spi/security/authentication/external/impl/jmx/Delegatee.java#L256]
> "use" it. However, the JCR users look like "valid" users then locally. Even
> if the authentication is done completely through the IDP and will fail
> properly for these missing users, it can be difficult for other uses like
> administration, monitoring, other application code to detect that such a user
> is not active anymore.)
