You can enable or disable the SSL security feature using rs_init, or you can use configure replication server with the use_ssl option.
To enable SSL with use_ssl, enter:
configure replication server set use_ssl to 'on'
Set use_ssl to “off” to disable SSL. By default, SSL is not enabled on Replication Server. When use_ssl is “off,” Replication Server does not accept SSL connections.
use_ssl is a static option. You must restart Replication Server after you change its value.
