The YaST CA Management module is Security and Users  CA Management.
But in the lab enviroment I can find it.
How can we install that module? I want to repete the lab 2.1 using this module.
According to the SUSE knowledgebase, the YaST Certificate Management Module is discontinued and has been removed. See more details here: https://suse.com/support/kb/doc/?id=000019721
