Hi @serverguru666, just wondering does mongoDB authenticationType have anything to do with this error that i get when i try mongodump using your connection format -
2020-05-31T23:53:02.921+0000 Failed: can't create session: could not connect to server: connection() : auth error: sasl conversation error: unable to authenticate using mechanism "SCRAM-SHA-256": (AuthenticationFailed) Authentication failed.

NB: The issue is that the command doesn't want me to add --password as plaintext, if i remove the --password flag it prompts me for password and works ok.

How to delete after 1 week please let me know..
