This article describes the configuration files and folders that come with Protocol Gateway

Each enrollment protocol is configured in a separate <protocol>.properties file and determines the following:

  • The flag to enable the protocol.
  • The names of the enrollment token procedures in CM server.
  • The name and location of any device RA token.
  • Any protocol specific configuration.

It is possible to override the cmHost and officer parameters specified in on a protocol and/or handler level. This makes it possible for different protocols and handlers to connect to different CF instances. See below for an example on how to configure cmHost and officer for a handler:

Example: How to configure cmHost and officer for a handler
handler.20.filter = certificates/[a-z0-9A-Z]+/details
handler.20.format = api/certificates-details
handler.20.cmhost = cf-host-ip
handler.20.officer.keyfile = protocol-gateway-vro-cf-host-ip.p12
handler.20.officer.password = <...>
