disabling mongo user
Instead of completely removing a Mongo database user, its better if there is option to disable user so that if there is any untoward incident we can enable it back. After observing for some time, we can delete/disable the user based on organization requirements. Its useful in some cases like mongo db user returned to same department after some time .
It can be very usefull if the database user can be automaticaly disable after x unsuccessfully login try.
