I thought you just needed to update the certificate. Why are you
creating a new replica?
My own StartSSL Server cert expires in a month and I just renewed it
this morning. They have a new subordinate CA, that might be part of the
problem (both sides need to trust it). I'd look in the access log of the
remote 389-ds server to see what error it threw (and the local one too I
suppose).
But really, you should be able to replace the certs using certutil, not
re-install the whole thing.
