              Install Certificate Authority root certificates on LCS

              Related Information

              Install Certificate Authority root certificates on LCS

              To support TLS encryption between IM and Presence and LCS, each LCS server must have a signed security certificate. This signed certificate, along with the root certificate of the Certificate Authority (CA) that signed the certificate, must be installed on each LCS server.

              Cisco recommends that LCS and IM and Presence servers share the same CA. If not, the root certificate of the CA that signed the IM and Presence certificates must also be installed on each LCS server.

              Generally, the root certificate of the LCS CA is already installed on each LCS server. Therefore, if LCS and IM and Presence share the same CA, there may be no need to install a root certificate. However, if a root certificate is required, see the following details.

              If you are using Microsoft Certificate Authority, refer to the following procedures in the Interdomain Federation for IM and Presence Service on Cisco Unified Communications Manager for information about installing the root certificate from the Microsoft Certificate Authority onto LCS:

              • Downloading the CA Certification Chain
              • Installing the CA Certification Chain

              If you are using an alternative CA, the following procedure is a generic procedure for installing root certificates onto LCS servers. The procedure for downloading the root certificate from the CA differs depending on your chosen CA.

              Before You Begin

              Download the root certificate or certificate chain from your CA and save it to the hard disk of your LCS server.

              Procedure
