The configuration file vault-config.properties must be placed under the directory $MID_SERVER_BASE_PATH/agent/properties The file location and name can be overriden by setting the MID_VAULT_CONFIG environment variable
Each property into the configuration file can have three kinds of values :
the value itself
the name of a MID server property (properties tab) prefixed by snc:. For example: snc:name_of_mid_property
the name of an environment variable prefixed by env:. For example: env:name_of_env_variable.
When a property value references a MID server property or an environment variable, these references will be resolved.
