If you have a wildcard certificate or a certificate signed for the PMP server name in a PFX or P12 format, you can directly apply it using the below-mentioned steps.
For webserver:
Copy your PFX file into <PMP_installation_directory>\conf folder.
• Navigate to the <PMP_installation_directory>\conf folder.
• Take a backup of the server.xml and gateway.conf present inside the <PMP_installation_directory>\conf folder. (Or take a snapshot)
• Login to PMP web UI as an Administrator and Navigate to Admin-->Configuration-->Password Manager Pro-->Server.
• Select the Keystore Type as PKCS12, browse for the keystore File(Your certificate.pfx or your certificate.p12) and password. Hit save.
• Restart the PMP server and connect through the web browser. If you can view the PMP login console without any warning from the browser, you have successfully installed your SSL certificate in PMP.
