Question: XMPP Federation over Expressway - Certificate SAN requirements

Hello world,

 

I read the "Chat and Presence XMPP Federation and Microsoft SIP Federation using IM and Presence or Expressway" document and stumbled accross a section that mentions the SAN field requirements for the Expressway-E Certificate. It mentions that "XMPP federation domains" should be listed in there. See screenshot. We are using DNS SRV records to discover other domains. Does that imply that everytime we want to federate with another domain the Expressway-E public certificate needs to be renewed?

 
Thank you in advance. Any input is appreciated.

It is your domains that you put there so you can assert yourself as that domain with trust when establishing TLS.

If you add additional domains to the Expressway for whatever reason then you have to have it re-issued.
