Introduction

The Infinite Scale Auth Machine service

Default Values

Auth Machine listens on port 9166 by default.

The `auth` Service Family

Infinite Scale uses several authentication services for different use cases. All services that start with auth- are part of the authentication service family. Each member authenticates requests with different scopes.

As of now, these `auth` services exist
auth-app	Handles 3rd party app authentication.
auth-basic	Handles basic authentication.
auth-bearer	Handles OIDC authentication.
auth-machine	Handles interservice authentication when a user is impersonated.
auth-service	Handles interservice authentication when using service accounts.

As of now, these auth services exist

auth-app

Handles 3rd party app authentication.

auth-basic

Handles basic authentication.

auth-bearer

Handles OIDC authentication.

auth-machine

Handles interservice authentication when a user is impersonated.

auth-service

Handles interservice authentication when using service accounts.

User Impersonation

When one Infinite Scale service is trying to talk to other Infinite Scale services, it needs to authenticate itself. To do so, it will impersonate a user using the auth-machine service. It will then act on behalf of this user. Any action will show up as action of this specific user, which gets visible when e.g. logged in to the audit log.

Deprecation

Note that with the upcoming auth-service service, the auth-machine service will be used less frequently and is probably a candidate for deprecation.

Configuration

Environment Variables

The auth-machine service is configured via the following environment variables. Read the Environment Variable Types documentation for important details. Column IV shows with which release the environment variable has been introduced.

master + Rolling 7.1.2

Environment variables for the auth-machine service
Name	IV	Type	Default Value	Description
`OCIS_TRACING_ENABLED` `AUTH_MACHINE_TRACING_ENABLED`	pre5.0	bool	false	Activates tracing.
`OCIS_TRACING_TYPE` `AUTH_MACHINE_TRACING_TYPE`	pre5.0	string		The type of tracing. Defaults to '', which is the same as 'jaeger'. Allowed tracing types are 'jaeger' and '' as of now.
`OCIS_TRACING_ENDPOINT` `AUTH_MACHINE_TRACING_ENDPOINT`	pre5.0	string		The endpoint of the tracing agent.
`OCIS_TRACING_COLLECTOR` `AUTH_MACHINE_TRACING_COLLECTOR`	pre5.0	string		The HTTP endpoint for sending spans directly to a collector, i.e. http://jaeger-collector:14268/api/traces. Only used if the tracing endpoint is unset.
`OCIS_LOG_LEVEL` `AUTH_MACHINE_LOG_LEVEL`	pre5.0	string		The log level. Valid values are: 'panic', 'fatal', 'error', 'warn', 'info', 'debug', 'trace'.
`OCIS_LOG_PRETTY` `AUTH_MACHINE_LOG_PRETTY`	pre5.0	bool	false	Activates pretty log output.
`OCIS_LOG_COLOR` `AUTH_MACHINE_LOG_COLOR`	pre5.0	bool	false	Activates colorized log output.
`OCIS_LOG_FILE` `AUTH_MACHINE_LOG_FILE`	pre5.0	string		The path to the log file. Activates logging to this file if set.
`AUTH_MACHINE_DEBUG_ADDR`	pre5.0	string	127.0.0.1:9167	Bind address of the debug server, where metrics, health, config and debug endpoints will be exposed.
`AUTH_MACHINE_DEBUG_TOKEN`	pre5.0	string		Token to secure the metrics endpoint.
`AUTH_MACHINE_DEBUG_PPROF`	pre5.0	bool	false	Enables pprof, which can be used for profiling.
`AUTH_MACHINE_DEBUG_ZPAGES`	pre5.0	bool	false	Enables zpages, which can be used for collecting and viewing in-memory traces.
`AUTH_MACHINE_GRPC_ADDR`	pre5.0	string	127.0.0.1:9166	The bind address of the GRPC service.
`OCIS_GRPC_PROTOCOL` `AUTH_MACHINE_GRPC_PROTOCOL`	pre5.0	string	tcp	The transport protocol of the GRPC service.
`OCIS_JWT_SECRET` `AUTH_MACHINE_JWT_SECRET`	pre5.0	string		The secret to mint and validate jwt tokens.
`OCIS_REVA_GATEWAY`	pre5.0	string	com.owncloud.api.gateway	The CS3 gateway endpoint.
`OCIS_GRPC_CLIENT_TLS_MODE`	pre5.0	string		TLS mode for grpc connection to the go-micro based grpc services. Possible values are 'off', 'insecure' and 'on'. 'off': disables transport security for the clients. 'insecure' allows using transport security, but disables certificate verification (to be used with the autogenerated self-signed certificates). 'on' enables transport security, including server certificate verification.
`OCIS_GRPC_CLIENT_TLS_CACERT`	pre5.0	string		Path/File name for the root CA certificate (in PEM format) used to validate TLS server certificates of the go-micro based grpc services.
`AUTH_MACHINE_SKIP_USER_GROUPS_IN_TOKEN`	pre5.0	bool	false	Disables the encoding of the user’s group memberships in the reva access token. This reduces the token size, especially when users are members of a large number of groups.
`OCIS_MACHINE_AUTH_API_KEY` `AUTH_MACHINE_API_KEY`	pre5.0	string		Machine auth API key used to validate internal requests necessary for the access to resources from other services.

YAML Example

Note the file shown below must be renamed and placed in the correct folder according to the Configuration File Naming conventions to be effective.
See the Notes for Environment Variables if you want to use environment variables in the yaml file.
