> My question is: Is there a limitation on filters in ldap?
There is no limit in theory. If there are problems, it's a bug of some
kind. But I've seen it work with filters more complicated than that,
so I don't know what's happening.

You might turn on debugging at the server (-d 1023 or something). It
might produce some illuminating information. If you can't figure it out,
send mail to ldap-support@umich.edu. When we get it figured out, we can
tell the whole list. ;-) -- Tim
