You should be able to customize the 'logged_in' template
(CMFDefault/skins/generic/logged_in.dtml or ../zpt_generic/logged_in.pt)
to remove the calls t 'member.setProperty'.

An alternative would be to tweak 'setProperty' so that it wrote back to
your LDAP server.  I'm not brave enough to try that, however :).
