Adding additional Alternative Names to keystore

Adding additional Alternative Names to keystore

Explorer

Hello, 

I have a request from seom developers to use aliases instead of hostnames of servers for their application. With a secured cluster setup I will need to add new SAN's (Subject Alternative Names) to the java keystores on each server. What is the best way to go about this? Is it better to simply re-create the keystore's for each server and re-import, or is there an easier solution to appened more SAN's to keystore files?

 

Thank you!
