You must manually export the DAS certificate using the following command:
appserver-install-dir/lib/upgrade/certutil -L -d appserver-instance-dir/config -n s1as -a -o sjsas.crt
This certificate will be required at the time of installing the load balancer plug-in.
The Application Server 9.1 installation program performs the following tasks for you.
Imports the DAS certificate by copying sjsas.crt to the apache-install-dir/conf/ssl.crt directory.
Appends the following lines to httpd.conf.
