LDAP plug in with Active Directory

I just installed the v1.70 RC17 and Login LDAP 1.01 plugin. I’ve followed some suggestions in the forum and GitHub issues, but to no avail.

I’m using [username]@ad.company.net for the User DN setting and specifying the OU where the users live for User Search DN setting. I only see the error:
“Could not complete search with dn “OU=Users,DC=ad,DC=company,DC=net”, query “sAMAccountName=” and filters “*”.”

Does this plugin only support traditional LDAP servers at this point?
