vSphere Replication appliance uses certificate-based authentication for all connections that it establishes with vCenter Server and remote site vSphere Replication appliances.
About this task
vSphere Replication does not use username and password based authentication. vSphere Replication generates a standard SSL certificate when the appliance first boots and registers with vCenter Server. The default certificate policy uses trust by thumbprint.
You can change the SSL certificate, for example if your company's security policy requires that you use trust by validity and thumbprint or a certificate signed by a certification authority. You change the certificate by using the virtual appliance management interface (VAMI) of the vSphere Replication appliance. For information about the SSL certificates that vSphere Replication uses, see vSphere Replication Certificate Verification and Requirements When Using a Public Key Certificate with vSphere Replication.
Prerequisites
Verify that the vSphere Replication appliance is powered on.
You must have administrator privileges to configure the vSphere Replication appliance.
You updated vCenter Server, the vSphere Client, Site Recovery Manager, and the Site Recovery Manager client to the corresponding 5.5.x update release.
Procedure
Results
You changed the SSL certificate and optionally changed the security policy to use trust by validity and certificates signed by a certificate authority.
If you change the SSL certificate, the vSphere Replication status changes to disconnected. Validate the certificate to reconnect the source and target sites before replicating a virtual machine.
