Active Directory - not getting group and users

The proxy is able to query Active Directory but as soon as I try and get users from a specific group it errors out:

[error] The Auth Proxy did not get results searching for users in DN DC=company,DC=org using the filter (&(|(memberof=CN=Duo Users,OU=Users,DC=company,DC=org))(|(&(objectClass=user)(objectCategory=person))(objectClass=inetOrgPerson)(objectClass=organizationalPerson))). It is likely that Duo would not be able to find specific users during authentication. Please confirm that DC=company,DC=org is the correct, fully qualified DN and that users should pass the filter.

[error] The Auth Proxy was not able to find the DN CN=Duo Users,OU=Users,DC=company,DC=org. Please confirm that DN exists and is accessible.

security_group_dn=CN=Duo Users,OU=Users,DC=company,DC=org

Once I remove the security_group_dn everything validates properly so I know it is binding to AD just fine.

Thank you for your help!

Never mind, I overlooked the fact that the Users folder is actually a container and not an OU hah!
