DNS discovery for OpenLDAP?

Hi all, In the course of my research into a solution involving Kerberos, OpenLDAP and OpenAFS (a.k.a. the Magic Trio), I've discovered that both Kerberos and OpenAFS support methods of DNS discovery, but that OpenLDAP apparently does not. Is this correct? If so, might there be a reason for this, other than that it has occurred to the developers, but that they just haven't had time yet to create it? It seems to me that it would be great to have. Thanks, Jaap
