Search for a DN

[<ra...@gm...>]

Hi 
 
A part of a script i made should search for the value of an Attribute in an
Entry and when the 
attribute does not exist or is empty it should search for the same one level
below. 
 
So far no problems... but to get the Entry wich is one level below the
starting entry i need to 
search fot a DN: 
 
original Entry eg: 
 
cn=item,cn=group,dc=host,dc=com		=> Here i cant find the value i need so... 
 
i search one level below: 
 
cn=group,dc=host,dc=com 
 
So i need to search for "cn=group,dc=host,dc=com". I recognized that i could
not use a DN in a filer 
argument ( "(dn=cn=group,dc=host,dc=com)" ) does not return any results. 
 
So how can i search for an DN or better: How can i get an Entry on wich i
know the DN? 
 
cheers, 
Raffaele
