Introduction

The Infinite Scale Auth Bearer service authenticates OpenID Connect bearer tokens.

Default Values

Users listens on port 9148 by default.

Built in OpenID Connect Identity Provider

A default Infinite Scale deployment will start a built-in OpenID Connect identity provider but can be configured to use an external one as well.

Scalability

There is no persistance or caching. The proxy caches verified auth bearer tokens. Requests will be forwarded to the identity provider. Therefore, multiple instances of the auth-bearer service can be started without further configuration. Currently, the auth registry used by the gateway service can only use a single instance of the service. To use more than one auth provider per deployment, you need to scale the gateway. This will change over time and be documented when available.

Configuration

Environment Variables

The auth-bearer service is configured via the following environment variables. Read the Environment Variable Types documentation for important details.

4.0.5

Environment variables for the auth-bearer service
Name	Type	Default Value	Description
`OCIS_TRACING_ENABLED` `AUTH_BEARER_TRACING_ENABLED`	bool	false	Activates tracing.
`OCIS_TRACING_TYPE` `AUTH_BEARER_TRACING_TYPE`	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_BEARER_TRACING_ENDPOINT`	string		The endpoint of the tracing agent.
`OCIS_TRACING_COLLECTOR` `AUTH_BEARER_TRACING_COLLECTOR`	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_BEARER_LOG_LEVEL`	string		The log level. Valid values are: 'panic', 'fatal', 'error', 'warn', 'info', 'debug', 'trace'.
`OCIS_LOG_PRETTY` `AUTH_BEARER_LOG_PRETTY`	bool	false	Activates pretty log output.
`OCIS_LOG_COLOR` `AUTH_BEARER_LOG_COLOR`	bool	false	Activates colorized log output.
`OCIS_LOG_FILE` `AUTH_BEARER_LOG_FILE`	string		The path to the log file. Activates logging to this file if set.
`AUTH_BEARER_DEBUG_ADDR`	string	127.0.0.1:9149	Bind address of the debug server, where metrics, health, config and debug endpoints will be exposed.
`AUTH_BEARER_DEBUG_TOKEN`	string		Token to secure the metrics endpoint.
`AUTH_BEARER_DEBUG_PPROF`	bool	false	Enables pprof, which can be used for profiling.
`AUTH_BEARER_DEBUG_ZPAGES`	bool	false	Enables zpages, which can be used for collecting and viewing in-memory traces.
`AUTH_BEARER_GRPC_ADDR`	string	127.0.0.1:9148	The bind address of the GRPC service.
`AUTH_BEARER_GRPC_PROTOCOL`	string	tcp	The transport protocol of the GRPC service.
`OCIS_JWT_SECRET` `AUTH_BEARER_JWT_SECRET`	string		The secret to mint and validate jwt tokens.
`OCIS_REVA_GATEWAY`	string	com.owncloud.api.gateway	The CS3 gateway endpoint.
`OCIS_GRPC_CLIENT_TLS_MODE`	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`	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_BEARER_SKIP_USER_GROUPS_IN_TOKEN`	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_URL` `OCIS_OIDC_ISSUER` `AUTH_BEARER_OIDC_ISSUER`	string	https://localhost:9200	URL of the OIDC issuer. It defaults to URL of the builtin IDP.
`OCIS_INSECURE` `AUTH_BEARER_OIDC_INSECURE`	bool	false	Allow insecure connections to the OIDC issuer.
`AUTH_BEARER_OIDC_ID_CLAIM`	string	preferred_username	Name of the claim, which holds the user identifier.
`AUTH_BEARER_OIDC_UID_CLAIM`	string		Name of the claim, which holds the UID.
`AUTH_BEARER_OIDC_GID_CLAIM`	string		Name of the claim, which holds the GID.
