I installed the Password Manager .bin file on the /opt partition on a Debian 12 server, so my <PMP-Home> is /opt/ManageEngine/PMP/. I installed it as root and I noticed pmp.service file was configured with a different user named "support" (is a user that exist) I changed the user in pmp.service file to root, and the service started successfully, but my web service didn't respond. So, I ran the ExecStart from pmp.service directly and this is the content:
