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>
