I'm new to SSL certificates and I'm wondering if there is any harm in installing multiple SSL certificates on a domain, or even on a single server. I'd like to install and SSL cert on my domain controller so that my firewall can use LDAP over TLS. But I'm a little nervous that installing a cert on my DC could cause my network to get wonky. Any help/suggestions are appreciated.

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.
