[rabbitmq-discuss] RabbitMQ 2.8.7 + LDAP + other_bind

[Marc]

Hello all!

For authentication I need to bind to a Microsoft Active Directory.

Let's say my bind user is '*uxxx*' with password '*pxxx*'.
Let's say the user I try to authenticate is '*uyyy*' with password '*pyyy*'.

I use the *other_bind<http://hg.rabbitmq.com/rabbitmq-auth-backend-ldap/file/d76afaf44415/README#l100>
* configuration option in order to bind with user '*uxxx*'.

Like this:

    { rabbit, [{auth_backends, [rabbit_auth_backend_ldap]}]},

    { rabbitmq_auth_backend_ldap, [

        {servers, ["myldapserver"]},

        {other_bind, {"uxxx", "pxxx"}},

        {dn_lookup_base, "DC=my,DC=domain,DC=com"},

        {dn_lookup_attribute, "AccountName"},

        {user_dn_pattern, 
> "CN=${username},OU=users,OU=mycompany,DC=my,DC=domain,DC=com"},

        {log,true}

    ]}


but when I try to login with user '*uyyy*' I get this in my logs:

                                 {simple,<<"pyyy">>}}

                              {'BindResponse',invalidCredentials,[],

                               asn1_NOVALUE,asn1_NOVALUE}},

                             asn1_NOVALUE}}


I understand the bind request is being forged with the wrong user.
Could that be a bug in the LDAP plugin?
