Well, that's just an index, right?  I want to be able to have a
handle/name/whatever, and put a phone number, RFID key, keypad code, et
cetera next to it; then when an auth event happens, I want to be able to
take the auth code (a phone number, RFID match, keypad code) and look up
the associated handle...

Yes, exactly.  In theory, the chains of trust all lead back to Kelly... she
says who the members are, and the members are allowed to give access to
others down the tree; in practice, this just means that everyone should
have a list of handles who have vouched for them; the system should follow
those handles up the tree until one of them reaches Kelly or we run out of
handles.

Yeah, I agree, this is an LDAP problem but OpenLDAP is terrible.  I thought
I remembered hearing about an alternative free LDAP last year that was OK?
 I don't remember what it was though.

The thing about OpenLDAP is, though, that there are lots of
readily-available management tools (like Gosa) that we can just plug into
the problem, and not have to write any of this ourselves.
