Sorry for my ignorance but what is gqView? I guess it has nothing to do
with basic LDAP
operations?

But in order to perform a search towards a LDAP server I need to set a
base. So....what base
should a set
(without knowing anything about server structure) in order to start a
"top" search?.....or
how can I get the
"root base" for the actual server?

In LDAPv3 I think this is placed in DSE attributetype "namingContexts"
(might be wrong here
thou) but for LDAPv2
I have no idea. This must be a quite basic question when starting a new
search  against an
"unknown" LDAP server.
