I would be very interested in this code as well.  I am just finishing a
port of the Netscape LDAP Java SDK into Smalltalk (including a set of
classes implementing BER).  The VisualWorks version is done and is being
tested, and I will be working on the Squeak version shortly.  I stayed
away from introducing local variables in blocks, etc. for just that
purpose.  The only missing pieces are UTF_8 string encoding (anybody
working on that?) and what to do with exceptions (any "official" word on
the status of Craig Latta's work being incorporated into the base
distribution?).

I didn't do anything special with X.509 certificates (just an attribute
value to LDAP), but there are obvious advantages to being able to work
with them directly as objects.  Now, perhaps I am glad!

If anyone is interested in the Squeak version of the LDAP SDK, please
drop me an (off-line) e-mail and I will let you know where to find it
when it is ready.
