Ok, this has a couple of problems:

firstly, it doesn't look like it can handle a result with multiple
occurances of the same attr. This is legal (I'm led to believe) and
made me rewrite the results section of my LDAP code. Currently I now
return a list of { 'name': 'foo', 'value':'bar' } dictionaries. I'm
not hugely happy with this, and have been considering a couple of 
options (see below).

secondly, how are ZLDAPEntries tied to the LDAP backend? Will changing
an attribute of an Entry object be automagically pushed through? will
there be any schema consistency checks?

on handling multiple values of the same attr:
thought 1: 
ignore them.
thought 2:
while thought 1 has advantages (simple implementation :), it's not
a good idea.
thought 3:
return multiples as a list
thought 4:
means all dtml has to check for a list. damn.
thought 5:
my new thought (as of earlier this week) was a new option for the
query of "handleMultiple". If this is set, the query will return
multiples as a list. This is optional, so that someone who doesn't
care about it doesn't have to do the work of checking if the value
is a list.

this bastard problem has stopped me releasing a new version for a while -
I'm spending most of the weekend at work tuning some databases (sql server
sucks so, so bad - it's even worse than Oracle), so I expect to get a new 
release done. if you have any patches, please fling them my way.
