Autostart Password Manager Pro on CentOS 7 with systemd

I followed instructions on https://www.manageengine.com/products/passwordmanagerpro/help/installation.html#start-lin for Linux and it generated Sys-V start/stop script (/etc/init.d/pmp-service) but service is not automatically starting after CentOS 7 server is rebooted.

Tried to enable the service via

systemctl enable pmp-service

but this fails with

pmp-service.service is not a native service, redirecting to /sbin/chkconfig.

Executing /sbin/chkconfig pmp-service on

service pmp-service does not support chkconfig

chkconfig --add pmp-service

fails with:

service pmp-service does not support chkconfig

I can manually start the PMP service without any issues.

I had a look at the startup script but was wondering whether ManageEngine has a systemd friendly version of autostart script that can easily be deployed.

Thanks a lot,

Hans
