Services don't typically require SSL.<br />
<br />
That said, these days, every service I setup for any client site I host is SSL wrapped.<br />
<br />
<a href="https://LetsEncrypt.org" rel="ugc"><u>https://LetsEncrypt.org</u></a> has provided free certs for years, so best SSL wrap all services which understand SSL.<br />
<br />
A domain server (if you're talking about bind/named/nsd/etc) understands SSL, because DNS isn't a protocol which requires securing.<br />
<br />
You'd use SSL or SSH to access your zone files + restart your domain server + the actual DNS protocol will be unencrypted.<br />
<br />
If I've misunderstood your question, add some clarification about what <b>domain server</b> might mean.

Hello,<br />
We are trying to find out if there are any circumstances whereby a login to a domain server requires an SSL certificate? If so, how can that certificate be identified, given there are multiple SSL certificates installed on this particular domain server?<br />
<br />
Thank you for any assistance

SSL Cert/Domain Login

HTTPS is a protocol for secure communication over a computer network which is widely used on the Internet. HTTPS consists of communication over Hypertext Transfer Protocol (HTTP) within a connection encrypted by Transport Layer Security (TLS) or its predecessor, Secure Sockets Layer (SSL). The main motivation for HTTPS is authentication of the visited website and to protect the privacy and integrity of the exchanged data. HTTPS is widely used for protecting page authenticity on all types of websites, securing accounts and keeping user communications, identity and web browsing private.
