Ok, see attachment. The problem is not reproducible with ldapsearch.

You're right, but it's a service vulnerability -- the server must be
online in order for our users to be able to log in.
In any case, I have a different configuration now, that solves the problem
in another way (by using two separate local databases -- one for the
translucent overlay and one for the subordinate directory.) Another
problem with the previous configuration was that I was getting "user
modification of overlay database not permitted" errors when using
ldapadd/ldapmodify (seems the translucent overlay can not be stacked with
the rwm overlay.)
