[rabbitmq-discuss] Creating an auth plugin (Kerberos)

[Simon Lundström]

Hm, I have a weird issue now that I can't debug since there is no log at
all.

I have configured my plugin to be used before the internal one:
{auth_backends, [rabbit_auth_backend_kerberos, rabbit_auth_backend_internal]},

And if I allow all login attempts in my plugin, noone (not "internal_admin"
specified in the internal database nor "virtual-user" which is supposed to be
able to access the system) can access the API (so it disables the CLI and
management GUI too).

However, if I deny all login attempts in my plugin internal_admin can login but
obviously not my virtual-user.

# rabbitmqadmin list users
+-------------------+--------------------------+---------------+
|       name        |        password_hash     |     tags      |
+-------------------+--------------------------+---------------+
| internal_admin    | the_password_hash_really | administrator |
| virtual-user      |                          | administrator |
+-------------------+--------------------------+---------------+
# rabbitmqadmin list permissions
+-------+-----------+------+-------------------+-------+
| vhost | configure | read |       user        | write |
+-------+-----------+------+-------------------+-------+
| /     | .*        | .*   | internal_admin    | .*    |
| /     | .*        | .*   | virtual-user      | .*    |
+-------+-----------+------+-------------------+-------+

As I said, there are no logs so I really have nothing to go on here = /

Oh, and here's the code

Thanks and have a great weekend!
