All,
I'm new to MongoDB and I was pulled into it when the vendor who setup our website left which means I'm learning everything from basic with a strong SQLServer DBA background.
On our Dev MongoDB V3.4.2 Windows installation, the vendor gave me a user named Monguser defined in admin with root as role and after they left I noticed Robo 3T as part of the installation.
When I try to connect via the mongo shell as below, I get an error with the message "Authentication failed". C:>mongo --username monguser --password mongold!234. I tried connecting to it via the Robo 3T and I'm able to connect via the same login/password.
Also, I was asked to create a backup of a database and I tried the following but it failed with the error Server returned error on SASL authentication step: Authentication failed for database MiningDB
C:\mongodump --username monguser --password mongold!234 --dbMiningDB
But if I run C:\mongodump --username monguser --password mongold!234 then it backs up all the databases in the installation without returning any error.
In both the cases, why am I getting the error? Any help will be deeply appreciated.
Thanks, rgn
OK. From the below link I figured out that I need to include "--authenticationDatabase admin"
