This change adds username and password configuration options to the client section of the configuration file. These options are used to create KMIP Credential objects for authenticating connections to a KMIP appliance. The KMIP proxy now uses these options when handling operation calls. If no credential is provided, the proxy will automatically create one from the config file. If either the username or the password is unspecified, an error is generated. If neither are specified, no credential is created. Only username/password credentials are currently supported. The KMIP proxy test suite now includes test cases covering this functionality.
