Hi all,
I see currently a memory leak with the LDAP stuff (although this was before with dynaload already, and even greater); the leak is proportional to the returned results (~ 200+ bytes per entry or so);
I compared with some samples from the Novell LDAP SDK, and found a free missing in our new ldap.c:

with this patch the memory leak is gone for me; however I was too lazy to lookup if the ldap_msgfree() call is also the right thing for OpenLDAP - can someone please check this, and comment?

greetz, Guen.
