GlobalSign

The CSC currently has an SSL Certificate from GlobalSign for *.csclub.uwaterloo.ca provided at no cost to us through IST. GlobalSign likes to take a long time to respond to certificate signing requests (CSR) for wildcard certs, so our CSR really needs to be handed off to IST at least 2 weeks in advance. You can do it sooner – the certificate expiry date will be the old expiry date + 1 year (+ a bonus ) Having an invalid cert for any length of time leads to terrible breakage, followed by terrible workarounds and prolonged problems.

When the certificate is due to expire in a month or two, syscom should (but apparently doesn't always) get an email notification. This will include a renewal link. Otherwise, use the IST-CA self service system. Please keep a copy of the key, CSR and (once issued) certificate in /home/sysadmin/certs. The OpenSSL examples linked there are good to generate a 2048-bit RSA key and a corresponding CSR. It's probably a good idea to change the private key (as it's not that much effort anyways). Just sure your CSR is for *.csclub.uwaterloo.ca.

At the self-service portal, these options worked in 2013. If you need IST assistance, ist-ca@uwaterloo.ca is the email address you should contact.

Certificate Location

Keep a copy of newly generated certificates in /home/sysadmin/certs on the NFS server (currently aspartame).

A list of places you'll need to put the new certificate to keep our services running. Private key (if applicable) should be kept next to the certificate with the extension .key.

• caffeine:/etc/ssl/private/csclub-wildcard.crt (for Apache)
• mail:/etc/ssl/private/csclub-wildcard.crt (for Apache, Postfix and Dovecot)
• rt:/etc/ssl/private/csclub-wildcard.crt (for Apache)
• mirror:/etc/ssl/private/csclub-wildcard.crt (for nginx)
• auth1:/etc/ssl/private/csclub-wildcard.crt (for slapd)
• auth2:/etc/ssl/private/csclub-wildcard.crt (for slapd)

Some services (e.g. Dovecot, Postfix) prefer to have the certificate chain in one file. Concatenate the appropriate intermediate root to the end of the certificate and store this as csclub-wildcard-chain.crt.
