Introduction

The Infinite Scale Auth Basic service provides basic authentication for those clients who cannot handle OIDC. This is a rare case, is usually not necessary and mainly used for tests or development.

The auth-basic service is responsible for validating authentication of incoming requests. To do so, it will use the configured auth manager, see the Auth Managers section. Only HTTP basic auth requests to ocis will involve the auth-basic service.

To enable auth-basic, you first must set PROXY_ENABLE_BASIC_AUTH to true.

The basic authentication implementation does not support cookies and is therefore not intended to be used for benchmarks.

Default Values

Auth Basic listens on port 9146 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.

Auth Managers

Since the auth-basic service does not do any validation itself, it needs to be configured with an authentication manager. One can use the AUTH_BASIC_AUTH_PROVIDER environment variable to configure this.

LDAP Auth Manager

Setting AUTH_BASIC_AUTH_PROVIDER to "ldap" will configure the auth-basic service to use LDAP as auth manager. This is the recommended option for running in a production and testing environment. More details on how to configure LDAP with ocis can be found in the admin docs.

Other Auth Managers

The possible auth mangers which can be selected are "ldap" and "owncloudsql". Those are tested and usable though "ldap" is the recommend manager. Refer to the admin docs for additional information about those.

Scalability

Scalability, just like memory and CPU consumption, are highly dependent on the configured auth manager. When using the recommended one which is "ldap", there is no persistance as requests will just be forwarded to the LDAP server. Therefore, multiple instances of the auth-basic service can be started without further configuration. Be aware, that other auth managers might not allow that.

Configuration

Environment Variables

The auth-basic 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.
