I got this from the manual: Note Replication configured over SSL with certificate-based authentication will fail in the following cases: * If the supplier's certificate is a self-signed certificate. _________ Is that still the case for FDS? Is there any way to get it working using self-signed certs? If not, I'm thinking of using stunnel between both masters, then. __________________________________________________ Do You Yahoo!?
