reverse search in dymanic group ?

Hi all,

I'm testing static group and dynamic group.

* Dynmaic group : is it possible to do reverse search in dynamic group ? I reead something about the "ismemberof" attribute and ds-virtual-static-group. But i'm not sure we can do it with openldap

* Static group seems to be fine for me. I have a newbie's question : can we have , for example, the mail attribute of all members of service Y in only one request ? I mean : make a request on service Y to have member's list and , in the same action , have the member's mail.

Thanks all.
