I can connect to the DB through terminal, but getting this error using mongoose and gulp.

MongoError: auth failed
My connection string is:
mongodb://usr:psw#localhost:27017/dbname
Any idea what it can be?

Answer 1

I installed MEAN from MEAN packaged by Bitnami for windows 7 using the following password: 123456
Syntax for connection string to connect to mongodb with mongoose module
mongoose.connect("mongodb://[usr]:[pwd]#localhost:[port]/[db]",{auth:{authdb:"admin"}});
If you don't have {auth:{authdb:"admin"}} in the connection string, you will get the following error: MongoError: Authentication failed.
JS Example: mongo-test/app.js
var mongoose = require('mongoose');
mongoose.connect('mongodb://root:123456#localhost/test',{auth:{authdb:"admin"}});
mongoose.set('debug', true); // turn on debug

Answer 2

just add ?authSource=yourDB&w=1 to end of db url
mongoose.connect('mongodb://user:password#host/yourDB?authSource=yourDB&w=1')
this work for me . &w=1 is important

Answer 3

There is many ways to make it work. This is what worked for me [mongoose v5.9.15] :
mongoose.connect('mongodb://localhost:27017/', {
auth: {
user:'root',
password:'example'
},
authSource:"admin",
useUnifiedTopology: true,
useNewUrlParser: true
})

You might want to do something like this...
var opt = {
user: config.username,
pass: config.password,
auth: {
authdb: 'admin'
}
};
var connection = mongoose.createConnection(config.database.host, 'mydatabase', config.database.port, opt);
'authdb' option is the database you created the user under.

Answer 5

mongoose.connect("mongodb://[host]/[db]", { auth:{
authdb: "admin",
user: [username],
password: [pw]
}}).then(function(db){
// do whatever you want
mongoose.connection.close() // close db
})

Answer 6

Do you have a user set up for dbname? By default, no user is required to connect to the database unless you explicitly set one. If you haven't, you should just try to connect to mongodb://localhost:27017/dbname and see if you still get an error.

Answer 7

I have found the solution hier, looks like when you create an user from the mongo shell, it makes SCRAM-SHA-1 instead of MongoDB-CR. So the solution to create a new user with MongoDB-CR authentication.
MongoDB-CR Authentication failed

Answer 8

just make sure that your database is created.
and also if your user is not added in the admin database, then make sure to add it by putting
db.createUser(
... {user:'admin',pwd:'admin',roles:['root']}
... )

This worked for me for mongod --version = db version v3.6.13
mongoose.connect('mongodb://localhost/expressapi', {
auth: {
authdb: "admin",
user: "root",
password: "root",
}
});

Answer 10

mongo mongodb://usr:psw#localhost:27017/dbname
Password should be alphanumeric only
User should be also available in db 'dbname' (Note : Even if user is super admin)
With above changes it connected successfully.

Answer 11

mongoose.connect("mongodb://[usr]:[pwd]#localhost:[port]/[db]",{ authSource: 'admin', useNewUrlParser: true, useUnifiedTopology: true });
I was getting same error. Resolved by adding authSource option to connect function solved the issue. see above code.

Answer 12

The connection string will be like
mongodb://username:password#localhost:27017/yourdbname?authSource=admin
