Only default password works in Perl RabbitMQ client

[Sherrod S]

Hello,

I just installed RabbitMQ 3.11.15 with 
Erlang 25.3.2 on Red Hat 7.9. Everything works except - my Perl  client - either Net::AMQP::RabbitMQ or Net::RabbitFoot - can only connect if the password is "guest". And that's true for any user account. rabbitmqctl authenticate_user works fine - so I suppose it's actually a Perl problem - but I'm just wondering if anyone has seen this? The error I get on the AMQP server is "AMQPLAIN login refused: user  '<any-user>' - invalid credentials". I tried configuring auth_backend in rabbitmq.conf - but since "internal" is the default - it didn't make a difference. When the connection succeeds - the log just says " accepting connection" - and doesn't log if it's "PLAIN",  "AMQPLAIN" or "EXTERNAL".

That's fairly odd. A sample of the code would be useful.

My code is pretty much the CPAN Net::AMQP::RabbitMQ "simple consumer.pl" -  but with a subroutine to process the queue messages once the connection is made. Of course the connection is never made - so I never get to processing the queue. I think it's just a bad install. I have another instance of  3.11.15 which works fine  - with the same code.
