Use a fully-qualified domain name for the SSL certificate common name
The server name specified in the directory service entry can be different from the common name the SSL server certificate uses to perform an SSL handshake. This allows you to use a fully-qualified domain name for the SSL certificate common name (for example, server1.bigcompany.com).
ase1 master tcp ether host_name port_number ssl="CN='common_name'" query tcp ether host_name port_number ssl="CN='common_name'"
When clients use SSL to connect to an Adaptive Server that also uses SSL, the SSL filter is placed after the port number in the interfaces file. The directory service includes the common name, which you add either by using dsedit or a text editor.
sp_listener includes the CN=common_name parameter, which allows you to specify a common name for the SSL certificate.
