You can replace the default StorageGRID server certificate with a single custom server certificate that allows users to access the Grid Manager and the Tenant Manager without encountering security warnings.
By default, every Admin Node is issued a certificate signed by the grid CA. These CA signed certificates can be replaced by a single common custom server certificate and corresponding private key.
Because a single custom server certificate is used for all Admin Nodes, you must specify the certificate as a wildcard or multi-domain certificate if clients need to verify the hostname when connecting to the Grid Manager and Tenant Manager. Define the custom certificate such that it matches all Admin Nodes in the grid.
You need to complete configuration on the server, and depending on the root Certificate Authority (CA) you are using, users might also need to install the root CA certificate in the web browser they will use to access the Grid Manager and the Tenant Manager.
