Setting up LDAP for OpenManage Enterprise 4.4

I've been going at this for a while and can't seem to find the right combination to get ldap auth working for OpenManage 4.4. I'm able to successfully connect with a Bind DN/Password, but the issue is that the Bind DN is of type CN while user logins are UID. So if I enter CN for "Attribute of User Login" I can successfully test a connection. However, when I try to import groups, it doesn't find anything.
