I have been bought SSL certificate from COMODO and I would like to install it on Univention, how to create CSR code for my PremiumSSL Wildcard Certificate.
The link below will help you install the SSL certificate
OP asked how to generate the CSR. This part is not explained in the SDB.
I guess that CSR Generation: Using OpenSSL (Apache w/mod_ssl, NGINX, OS X) provides the missing informations.
