Auth-Basic

Abstract

The oCIS Auth Basic service provides basic authentication for those clients who cannot handle OpenID Connect. This should only be enabled for tests and 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.

Example Yaml Config

The `auth` Service Family

ocis uses serveral 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 services exist:

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_MANAGER environment variable to configure this. Currently only one auth manager is supported: "ldap"

LDAP Auth Manager

Setting AUTH_BASIC_AUTH_MANAGER 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

oCIS currently supports no other auth manager

Scalability

When using "ldap" as auth manager, 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.
