I think the easiest thing to do here would be to refine your LDAP string.
(LDAP syntax is confusing because several different looking syntaxes are
allowed - it's not consistent. I'll show you one syntax that should work -
there are others.) Let's say you had on the jrcc.local domain an OU called
MyBusiness (common), and then below that an OU called Users. You would use
LDAP://OU=Users,OU=MyBusiness,DC=jrcc,DC=local

That sets your LDAP path to point to that node, your filter does the rest of
the work. Although you might find you don't need your filter anymore.
