LDAP query trouble

Hello all, I have a, somehow, working postfix + dovecot configuration with AD LDAP lookups. Recently I have moved our AD to a samba4 server with the unfortunate result, that sending mail now is very slow. This is because of the, currently, slow LDAP server implementation in samba4 which handels th
