Active directory not populating correctly

I believe i must have a container/link wrong somewhere - the names are coming in, but there is other additional information showing up as well. Some examples:

from openfire - users/groups - I get this information or information like it:

most names are fine - but for example, artroom$ and bandroom$ are computers. ok, i just figured that out.

I only want DOMAIN USERS listed - - but unfortuantely, when i followed the video to create the domain list and share it to spark,

(under group summary, the domain users are NOT listed there).

my domain is stbernardcampus.local

a few properties:

ldap.baseDN: DC=stbernardcampus,DC=local

ldap.adminDN: administrator@stbernardcampus.local

should my basedn be users ? domain users?
