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
