dynamic groups

Hi,

I have built my ldap groups with dynlist overlay.

_If i search for a group i can see the members: ldapsearch -Y EXTERNAL -b 'ou=Groups,dc=abc,dc=net' 'cn=ou-is' dn: cn=ou-is,ou=Groups,dc=abc,dc=net objectClass: groupOfURLs objectClass: fhvGroup cn: ou-is memberURL: ldap:///ou=People,dc=abc,dc=net??sub?(fhvIsAISMemberOf=cn=ou-is,ou=Groups,dc=abc,dc=net) member: uid=cb,ou=fhv,ou=People,dc=abc,dc=net

_But if i search for members i only get empty results: ldapsearch -Y EXTERNAL -b 'ou=Groups,dc=abc,dc=net' '(member=uid=cb,ou=fhv,ou=People,dc=abc,dc=net)' cn member

Is this not working with dynamic groups?

And does it make sense to build indexes for dynamic member attributes?

/thx,chris
