Re: Replica (ldap slave server) certificates (SSL/TLS). Are clients certificates needed?

I'm newbie in mailman list, so I don't know if I'm sending this email correctly.

Tranks for your reply, and what I've understood, I have to do the following:
% cd /var/myca/
% /usr/share/ssl/misc/CA.sh -newca
This creates cacert.pem and private/cakey.pem (these files are common for all the server and clients). In The field of Common Name I have to write the ldap master server name host (i.e. ldap.dominio.com).

Now, I make a singing request for master server, slave server (replica) and clients. I execute all these command for each one changing the Common Name for the specific host name (for master server: ldap.dominio.com, for slave server (replica):replica.ldap.dominio.com, for clients: pc1.dominio.com....).
% openssl req -newkey rsa:1024 -nodes -keyout newreq.pem -out newreq.pem
% /usr/share/ssl/misc/CA.sh -sign

Are all OK?
Thank you very much, and if this is correct, you could add this to a FAQ of the openldap guide, because I haven't seen anything about slave servers.

For all server and clients certs you have created or will create, just sign them
all with the CA cert you created and make sure all servers and clients get a copy
of the CA cert. That's all you need to do.
