How to uploade a certificate

If you sent the certificate to a Certificate Authority and have received the signed certificate file, upload the file to the SolarWinds N-central server.

  1. Click Administration > Certificate Management > Upload Certificate.
  2. Select the Type of certificate to be uploaded from one of the following:
    • CA Certificate
    • SSL Certificate
    • UCC/Wildcard Certificate

    CA certificate list files must be uploaded as a PEM, DER, or PKCS#12 file.

  3. Click Browse to navigate to the file.
  4. If you are uploading a UCC/Wildcard Certificate, type the Password required to encrypt and decrypt the file.

  5. Click Save.

After the specified certificate is uploaded, SolarWinds N-central ensures that the certificate matches the current key and restarts the appropriate services for the certificate to take effect.

Certified Authority certificates

If the proper CA certificate file is not uploaded, the HTTPS service cannot monitor the associated SSL certificates installed on a customer's devices.

Uploading a customer's CA file allows SolarWinds N-central to monitor customized SSL certificates that have been signed by the CA and installed on a customer's devices. The SSL certificates can be monitored for their validity and expiry dates using the HTTPS service.

A CA certificate in SolarWinds N-central is a file containing a list of names and public keys of the certificate authorities. By default, SolarWinds N-central already provides a CA certificate file, which lists the certificates of the industry-recognized CAs, allowing any SSL certificate signed by one of these authorities to be monitored.

When a CA file is uploaded, the SolarWinds N-central server and Windows Probes download the file and use it when monitoring the associated SSL certificates. During the upload, a previously uploaded CA file is replaced. The file provided by SolarWinds N-central, however, is always retained on the central server. Therefore, we recommend that you maintain one CA certificate file and append it with the new CA certificate file you receive. This updated file can then be uploaded, allowing the monitoring of new SSL certificates while retaining the previous CA certificates.

If you upload a CA certificate that is not included in the CA certificate file, it must be uploaded in the chained format. To create a chained format, append the signed certificate to the CA certificate. Refer to Certificate management for more information on chained certificates.

Unified Communications Certificate

A UCC is an SSL certificate that secures multiple domain names and host names within a single domain name. A UCC allows you to secure a primary domain name and up to ninety-nine (99) additional Subject Alternative Names (SANs) within a single certificate. UCCs are particularly suited for Exchange Server 2007, Exchange Server 2010, and Live Communications Server.
