Dynlist query

[Guy Deleeuw <G.De_Leeuw@eurofer.be>]

Hi all

I have a small problem that require your advice.
We try to query our ldap database from dynlist entries :

We have a tree like :
testGroup ....
- member
- manager
group2
- member
- manager

ect..

Each member entry is a dynlist, which have a dynamic multivalued 
attribue : "ExoMemberShipMember"

I have on our slapd.conf this line :
dynlist-attrset ExoMemberShip ExoMemberShipURL ExoMemberShipMember



Now, I start a ldapsearch to show if the dynamic attribute is correctly 
populated :
root@nova:~# ldapsearch -x -LLL -b 
"ou=groups,ou=portal,ou=www,ou=Exo,o=Eurofer,c=be" -s sub 
"(&(&(objectClass=ExoMemberShip)(ExoMemberShipURL=*)))"

dn: cn=member,ou=testGroup,ou=groups,ou=portal,ou=www,ou=Exo,o=Eurofer,c=be
objectClass: ExoMemberShip
objectClass: top
cn: member
description: member
ExoMemberShipURL: ldap:///br=Internal,o=Eurofer,c=be??sub?(uid=*)
ExoMemberShipMember: cn=Cassou-Mounat Dominique,br=Internal,o=Eurofer,c=be
ExoMemberShipMember: cn=Caufriez Freddy,br=Internal,o=Eurofer,c=be
....
....
dn: cn=member,ou=group2,ou=groups,ou=portal,ou=www,ou=Exo,o=Eurofer,c=be
objectClass: ExoMemberShip
objectClass: top
cn: member
description: member
ExoMemberShipURL: ldap:///br=Internal,o=Eurofer,c=be??sub?(uid=*)
ExoMemberShipMember: cn=Cassou-Mounat Dominique,br=Internal,o=Eurofer,c=be
ExoMemberShipMember: cn=Caufriez Freddy,br=Internal,o=Eurofer,c=be
...
...


All work fine, I can retrieve the two group entries.

Now, I try to retrieve the group which have a particular member 
(ExoMemberShipMember):
ldapsearch -x -LLL -b "ou=groups,ou=portal,ou=www,ou=Exo,o=Eurofer,c=be" 
-s sub 
"(&(&(objectClass=ExoMemberShip)(ExoMemberShipURL=*))(ExoMemberShipMember=cn=De 
Leeuw Guy,br=Internal,o=Eurofer,c=be))"


And I receive an empty respond.

Could you give me your advice about the feasibility of this kind of query ?

Thanks in advance for your respond

Guy
