OK. Lemme try again: why is the LookupFilter.filter(Name dn) dn paramter 
always empty? (Or perhaps, what sort of query would set it?)

OK. I guess ldapsearch is forgiving my bad syntax as I get the same result 
with both. I'll use '(cn=a b)' from now on.

Sorry. I'll try again.

I have this entry:
cn=a b,ou=super,ou=contacts,uid=6760,dc=home2,dc=mark

I connect with a baseDN of ou=super,ou=contacts,uid=6760,dc=home2,dc=mark

I have this query: '(cn=a b)'

I have successfully inserted my own SWLookupFilter into eve.

SWLookupFilter.filter(LdapContext ctx, Name dn, Attributes entry) is called 
and I print out "dn" and "entry". I get the following:

dn: empty
1. Apache Software Foundation
2. ou=system
3. dc=home2,dc=mark
4. cn=schema,ou=system

The problem/question is this: how is it possible for SWLookupFilter to do any 
sort of filtering or query rewriting when SWLookupFilter isn't presented with 
the query or baseDN? perhaps the baseDN is available in the LdapContext but 
looking at the API doesn't reveal it (to me at least).

Shouldn't the query be in the attributes? Or am I misunderstanding the purpose 
of the "Attributes entry" parameter?

Thank you.
