1. How can i add a second base DN using the new cn=config files ?

I've got a "dn=domain1.org,dn=org", i'd like to add a "dn=domain2,dn=org" base.

That should be dc=domain1,dc=org and dc=domain2,dc=org. "dc" means domain component.

The simplest way is to make "dc=org" your top DN and add the two subdomains below that. The other way is to make two databases, each with its own suffix, directory, etc.

2. How can i set TLS using the new cn=config style ?

Start with the Admin Guide for TLS in general, and use the attributes listed in TLS OPTIONS in the slapd-config manpage.

Or write slapd.conf first according to the Admin Guide and then use sbin/slaptest -f <slapd.conf filename> -F <slapd.d directory> to convert to cn=config format.
