alias dereferencing versus referrals

[Nuno Miguel do Espirito Santo Gomes de Oliveira <NOliveira@eid.pt>]

This is my second post of this cry for help:

Imagine the following DIT :

(DSA_1)
dn: c=pt
dn: ou=orgA, c=pt (objectClass referral, extensibleObject/ ref =
<DSA_2>/ou=orgA,c=pt)
	|
	| (DSA_2)
	dn: ou=orgA, c=pt(objectClass:organizationalUnit)
	dn: ou=orgAUnit, ou=orgA, c=pt(objectClass:organizationalUnit)

Imagine further that we're connected to DSA_1, and that we're not following
or handling referrals or continuation references.

The problem is that whenever I set alias dereferencing to FINDING, a search
with base ou=orgAUnit, ou=orgA, c=pt returns NoSuchObject. However, by
setting it to SEARCHING I get a ReferralError, which was my expected result.
The fact that alias dereferencing settings affect the search result WHEN NO
ALIASES ARE INVOLVED seems strange to me.

This must be a problem with the server rigth?
If so, is this behaviour according to any standard? More important, IS THIS
A BUG? 

Please, I really need help on this.
Thank you, 
Nuno.
