Bolke de Bruin commented on RANGER-980:
---------------------------------------
If we can combine option 2 with option 1 it would be perfect (I dont think they
are mutually exclusive). Obviously Option 1 part should be configurable (as you
mentioned), I am just a bit weary of Ranger's DB growth and no pruning (this is
already an issue for us).

>
> usersync for all sources creates users and groups, but does not delete them
> from Ranger's database if these users and groups do not exists anymore in the
> original source.
> So if you have for example a user called "bob" and bob leaves the company his
> access rights will continue to exist in Ranger. If a new employee comes in
> that is also "bob" he is immediately granted the same access as the previous
> employee. This creates security incidents.
> In a reasonable complex company it cannot be expected that another user
> administration is being taken care of, while deletion could and should happen
> automatically.
