Mongodb Auth

[IharKrasnik]

Hi!

As far as I found there is no way to set mongodb database users/superusers via the role. The single possible setting that I see is mongodb_conf_auth variable that can be set to rather yes or no and that's it. Are there any plans on adding support for it or this setting kept simple by some reason?

Could you please provide an example of creating mongodb superuser?

P.S. thank you for supporting such a simple and stable playbook, we're using it on production for a long time
