Server FQDN

Hello! I’m plan to deploy Openfire Server. My parent domain for example is contoso.com. So I’m install application with domain name contoso.com and server name is openfire.contoso.com.

Server Properties:


Server Uptime: 6 minutes – started May 31, 2017 1:38:20 PM

Version: Openfire 4.1.4

Server Directory: C:\Program Files (x86)\Openfire

XMPP Domain Name: contoso.com

Environment:


Java Version: 1.8.0_131 Oracle Corporation – Java HotSpot™ Client VM

Appserver: jetty/9.2.z-SNAPSHOT

Server Host Name (FQDN): openfire.contoso.com

OS / Hardware: Windows Server 2012 R2 / x86

Locale / Timezone: en / Moscow Standard Time (3 GMT)

OS Process Owner: Administrator

Java Memory: 32,42 MB of 247,50 MB (13,1%) used

My question is: for what domain should I make a certificate. For openfire.contoso.com (because clients perform connection to this host name) or for contoso.com? Through the web interface of the server, it wants to do just that for contoso.com.

Contoso.com as you clients should login to contoso.com, not to server’s hostname.
