[rabbitmq-discuss] rabbit_auth_backend_ldap and Active Directory

Tue Jan 8 18:51:51 GMT 2013

Got it working.

Thought I'd pass along the config I used.  I was not able to login with a user_dn_pattern of just ${username}, so I guess my solution wouldn't do well in a forest of multiple domains, but it works for me.

I hadn't noticed the {log, network}, option before, so that helped in the debugging.

Thanks again.

Hi. dn_lookup_base and dn_lookup_attribute should do what you want. I would expect something like:

  {dn_lookup_base,      "OU=Users,DC=corp,DC=example,DC=com"},
  {dn_lookup_attribute, "sAMAccountName"}

should work.

Do the logs (in 'network' mode) not show a search after the bind?

If not: which version of RabbitMQ are you using? Can you post your config, and a screenshot or similar showing your account in AD?

Cheers, Simon
