NO.  The DN you get back is the DN of the entry, not the DN of the
alias.

In the example I gave 

   l=europe @ o=Cosine @ ou=paradise @ cn = Colin Robbins

is an alias pointing to 

   c=GB @ o=X-Tel Services Ltd @ cn=Colin Robbins

If I subtree search below l=Europe @ o=Cosine the search will return
the DN  c=GB @ o=X-Tel Services Ltd @ cn=Colin Robbins.   I have no
way of finding out that this was returned because of the 
l=europe @ o=Cosine @ ou=paradise @ cn = Colin Robbins alias.

Also, in my example, I suggested a search for
"alias object name = c=GB @ o=X-Tel Services Ltd @ cn=Colin Robbins",
would solve the problem.  Having thought about it a bit more, I
realise even this will not work if there are multiple aliases in the
subtree.

I still believe there is a real problem with managing aliases in the
DIT using DAP alone.
