How to verify a RabbitMQ user password?

Question

Is there a simple method to verify a RabbitMQ user password from command line? By simple I mean:

• without rabbitmq_management plugin enabled

• without extra dependencies, like ruby/python/etc. libraries not usually present on a Linux machine by default.

Answer 1

sudo rabbitmqctl authenticate_user <username> <password>

If the password is appropriate it shows:

Authenticating user "username"
Success

If the password is wrong it shows the below:

Authenticating user "username"
Error: failed to authenticate user "username"

Answer 2

• There is rabbitmqctl authenticate_user
• rabbitmqadmin can be used if the user has the management tag (which can be added temporarily)
• Alternative authN backends have more options: LDAP tooling for the LDAP backend, curl for the HTTP backend and so on.

Answer 3

You can attempt to login with the username/password using rabbitmqadmin, although this is not included by default when installing RabbitMQ.

IMHO the simplest thing to do is write a Python script that connects to RabbitMQ, but this requires either a) the Kombu library or equivalent, or b) writing your own minimalistic AMQP client.
