How many SSO certificates do I need ?

Hello,

We are going to install 4 EP 7.0 (DEV,PRJ,ACC,PRD).

We will install 3 Web Dispatcher 1 for PRD, 1 for PRJ and 1 for DEV & ACC.

We are going to use Verisign self signed certificates Certificates.

For me we need 1 for the PRD and 1 for the PRJ.

But my question is how many certificates do I need for my DEV & ACC as they will be linked to the same Web Dispatchers (different port off course).

Can I use the same certificates for both DEV & ACC (there will be install on the same hosts) ?

Or do I need a separate certificates for my DEV & ACC ?

Many thanks in advance for your feedback.

Dom./
