command line authentication of mongo fails

I am running mongo 2.2.2 on osx.

When I do the following authentication is going fine:

$ mongo
>> use admin
>> db.auth("uname", "password")

log:

Thu Mar 7 13:51:08 [initandlisten] connection accepted from 127.0.0.1:63474 #10 (4 connections now open)
Thu Mar 7 13:51:08 [conn10] authenticate db: admin { authenticate: 1, nonce: "123", user: "uname", key: "456" }

However when I try to authenticate directly from the commandline:

$ mongo admin -u uname -p password

I get the following error:

Thu Mar 7 14:25:52 [initandlisten] connection accepted from 127.0.0.1:63939 #12 (5 connections now open)
Thu Mar 7 14:25:52 [conn12] authenticate db: admin { authenticate: 1, nonce: "789", user: "uname", key: "147" }
Thu Mar 7 14:25:52 [conn12] auth: key mismatch uname, ns:admin
Thu Mar 7 14:25:52 [conn12] end connection 127.0.0.1:63939 (4 connections now open)

Does anyone know what causes this?

A password containing special characters, especially the dollar sign, has to be put in single quotes to protect them from the command shell:


$ mongo admin -u uname -p 'password'

**This is the way to access an authenticate MongoDB database from terminal**

mongo -u user_name -p "your_password" host_name/database_name

**Ex:**

mongo -u hasib -p "123456" localhost/my_db

To Login to MongoDB Via Command Line do the following

$ mongo admin -u 'username' -p 'Password'

You have to use the `--authenticationDatabase` to indicate mongodb where to find the user you have created. For example:

mongo admin -u uname -p 'password' --authenticationDatabase admin

You could also connect using the mongo connection URL as follow:


mongo "mongodb://<user>:<password>@<host: 127.0.0.1>:<port: 27017>/<db_name>?authSource=admin"

- The db_name is optional.
- The host is usually 127.0.0.1 if you are
connection to localhost.
- The port is usually 27017.
