RabbitMQ ::: Multiple DN ( Distinguished Name ) Patterns for LDAP

Question

I need to add multiple DN (Distinguished Name) patterns to allow users from multiple OUs to login .

Kindly suggest .

I have added the below configuration to 'advanced.config' file ::

[
    {rabbit, [
        {auth_backends, [rabbit_auth_backend_ldap]}
    ]},
    {rabbitmq_auth_backend_ldap, [
        {servers,         ["---.---.---.---"]},
               {dn_lookup_attribute, "distinguishedName"},
        {dn_lookup_base,"OU=--,DC=--,DC=--,DC=com"},
               {
                user_dn_pattern,{'or',
                                    [
                                        {"CN=${username},OU=<OU_1>,OU=Standard,OU=Users,DC=net,DC=<org>,DC=com"},
                                        {"CN=${username},OU=<OU_2>,OU=Standard,OU=Users,DC=net,DC=<org>,DC=com"}    
                                    ]       
                                }
                },                 
               {port, 636},
               {log, network},
        {tag_queries, [
            {administrator, {in_group,"CN=<Group Name>,OU=Security,OU=Groups,DC=net,DC=<org>,DC=com"}},
            {management,    {in_group,"CN=<Group Name>,OU=Security,OU=Groups,DC=net,DC=<org>,DC=com","member"}}
        ]},
        {vhost_access_query, {constant, true}}
    ]}
].

With the reference to https://www.rabbitmq.com/ldap.html , 'Boolean Queries' I have added 'or' in user_dn_pattern .

Can you please share suggestions for this ? How we can add 2 user_dn_patterns for this ?

• Tried to combine 2 DN patterns using Boolean based queries in LDAP for RabbitMQ .

However, it is not working .
