The Eudora 4.3  filter says:

	IF there exists a "cn" attribute
	OR <nothing specified>
	THEN return the entry

Not technically correct, but, as you say, it appears to work.

The first Outlook 5.0.2 search filter should return the
same results as the Eudora 4.3 search filter, at least
from the information you have provided:

	IF there exists a "givenname" attribute
	OR there exists an "sn" attribute
	OR there exists a "cn" attribute
	OR there exists a "mail" attribute
	THEN return the entry

The Outlook 5.02 "simple filter" has an incorrect nesting depth
for parenthesis; it should still work, according to the RFC, as:

	IF there exists a "cn" attribute
	OR <nothing specified>
	OR there exists a "mail" attribute
	THEN return the entry

This may have something to do with your use of colon (:)
instead of equals (=) in your LDIF, if that's really LDIF
and not something you just typed in.

Otherwise, I would look to see how they are binding; I
rather suspect that the Microsoft binding process favors
LDAPv3 and Exchange.

Alternately, it's just another bug in Outlook.

Netscape is unfortunately incompatible with most of the
recent popular email worm/virus distributions, so it's
understandable that they do that to maintain compatability.
