This feature allows to fetch keyblock by keyblock from an LDAP server.
This way tools can process and maybe filter each keyblock in a more
flexible way. Here is an example where two keyblocks for one mail
address are returned:

$ gpg-connect-agent --dirmngr
> ks_get --ldap --first  <foo@example.org>
[... First keyblock is returned ]
OK
> ks_get --next
[ ... Next keyblock is returned ]
OK
> ks_get --next
ERR 167772218 No data <Dirmngr>
