I have a question related to authentication when using a mongodb replica set.
Is it possible to set a mongodb replica set, where an authentication is going to be required from any coming user (client), but without a key-file and authentication between the members of the set?
M310 course, the two lectures related to my question are: Enabling SCRAM-SHA-1 and Enabling Internal Authentication.
But looking at them again did not seem to give me an answer (to this particular case). I hope the question is clear enough and someone can easily answer by YES or NO.
