server returned error on SASL authentication step: Authentication failed

Question

The following is my MongoDB connection dial from GoLang. But it\'s returning a panic \"server returned error on SASL authentication step: Authentication failed.\".

Answer 1

mgo returns this error if username, password or database are wrong. Check your credentials twice. There are no other situations when you can see Authentication failed error message.

Answer 2

I got this error while using a connection string from a Heroku app by means of the --uri flag. What solved it in my case was adding the database name with -d:

mongodb_uri="$(heroku config:get MONGODB_URI -a myapp)"
mongorestore --uri=$mongodb_uri -d heroku_7m41q4xs db/

Answer 3

I faced similar error and added --authenticationDatabase parameter and it worked while we connecting to a remote MongoDB

Use the similar below format in your code :

$mongorestore --host databasehost:98761 --username restoreuser
--password restorepwd --authenticationDatabase admin --db targetdb ./path/to/dump/

Answer 4

I got my answer from this link: https://newbiedba.wordpress.com/2016/11/21/mongodb-3-2-server-returned-error-on-sasl-authentication-step-authentication-failed/

Except for all answers above, the only unmentioned reason is that my password has a special character '$' in it. I think this is a very common practice to have special characters and this may trip many without this simple tip:

When using command line mongo/mongostat/etc.. Single quote your username or password that has special characters!

Answer 5

I had the same error when using with dokku mongo:import . In my case I included dot(period) in my db name

You shouldn't include dot in your mongodb name when 'dokku mongo:create ' I've changed it to seunghunlee instead of seunghunlee.net now this command works

dokku mongo:import seunghunlee < seunghunlee.net.dump.gz

Hope it helps!

Answer 6

The error you report seem the cause of the authentication fail is caused by a nil pointer, you should check the data before using them to create the connection
