Help removing OD replica

Hi there,

I'm trying to remove an old replica left over from a host name change. In terminal, sudo slapconfig -removereplica IPADDRESS does nothing but it does produce the following:

2015-02-26 04:31:31 +0000 slapconfig -removereplica

2015-02-26 04:31:31 +0000 command: /usr/bin/kdestroy --credential=ldap/IPADDRESS@DOMAIN

Trying the same in server.app results in the following message:

"The certificate for this server is invalid. You might be connecting to a server that is pretending to be “COMPUTER NAME” which could put your confidential information at risk."

I'm using the same self-signed cert on both master and replica

Is there any way to get this done?

Thanks.
