Auth App Service Configuration
Introduction
The Infinite Scale Auth App service provides authentication for 3rd party apps.
With the auth-app
service, you can create tokens that can be used to authenticate 3rd party apps accessing Infinite Scale.
To enable auth-app
, you first must set PROXY_ENABLE_APP_AUTH
to true
.
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 |
|
---|---|
Handles 3rd party app authentication. |
|
Handles basic authentication. |
|
Handles OIDC authentication. |
|
Handles interservice authentication when a user is impersonated. |
|
Handles interservice authentication when using service accounts. |
Service Startup
-
Because this service is not started automatically, a manual start needs to be initiated which can be done in several ways, only one example is shown below. For more details see the Start Infinite Scale section.
-
To configure the service usage, an environment variable for the proxy service needs to be set to allow app authentication.
OCIS_ADD_RUN_SERVICES=auth-app # deployment specific. Alternatively you can start the service explicitly via the command line.
PROXY_ENABLE_APP_AUTH=true # mandatory, allow app authentication. In case of a distributed environment, this envvar needs to be set in the proxy service.
App Tokens
App Tokens are used to authenticate 3rd party access via https like when using curl (apps) to access an API endpoint. These apps need to authenticate themselves, as no logged in user authenticates the request. To be able to use an app token, one must first create a token via the cli. Replace the user-name
with an existing Infinite Scale user. For the token-expiration
, you can use any time abbreviation from the following list: h, m, s
. Examples: 72h
or 1h
or 1m
or 1s.
Default is 72h
.
ocis auth-app create --user-name={user-name} --expiration={token-expiration}
Once generated, these tokens can be used to authenticate requests to ocis. They are passed as part of the request as Basic Auth
header.
Configuration
Environment Variables
The auth-app
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.

The bind address of the HTTP service. |
|
pre5.0 |
string |
/ |
Subdirectory that serves as the root for this HTTP service. |
|
pre5.0 |
[]string |
[*] |
A list of allowed CORS origins. See following chapter for more details: Access-Control-Allow-Origin at https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Access-Control-Allow-Origin. See the Environment Variable Types description for more details. |
|
pre5.0 |
[]string |
[GET POST DELETE] |
A list of allowed CORS methods. See following chapter for more details: Access-Control-Request-Method at https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Access-Control-Request-Method. See the Environment Variable Types description for more details. |
|
pre5.0 |
[]string |
[Authorization Origin Content-Type Accept X-Requested-With X-Request-Id Ocs-Apirequest] |
A list of allowed CORS headers. See following chapter for more details: Access-Control-Request-Headers at https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Access-Control-Request-Headers. See the Environment Variable Types description for more details. |
|

bool |
true |
Allow credentials for CORS.See following chapter for more details: Access-Control-Allow-Credentials at https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Access-Control-Allow-Credentials. |
|
pre5.0 |
bool |
false |
Activates TLS for the http based services using the server certifcate and key configured via OCIS_HTTP_TLS_CERTIFICATE and OCIS_HTTP_TLS_KEY. If OCIS_HTTP_TLS_CERTIFICATE is not set a temporary server certificate is generated - to be used with PROXY_INSECURE_BACKEND=true. |
|
pre5.0 |
string |
|
Path/File name of the TLS server certificate (in PEM format) for the http services. |
|
pre5.0 |
string |
|
Path/File name for the TLS certificate key (in PEM format) for the server certificate to use for the http services. |
|
next |
string |
|
The secret to mint and validate jwt tokens. |
|
pre5.0 |
string |
com.owncloud.api.gateway |
The CS3 gateway endpoint. |
|
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. |
|
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. |
|
next |
bool |
false |
Disables the encoding of the user’s group memberships in the access token. This reduces the token size, especially when users are members of a large number of groups. |
|
next |
string |
|
The machine auth API key used to validate internal requests necessary to access resources from other services. |
|
next |
bool |
false |
Allows admins to create app tokens for other users. Used for migration. Do NOT use in productive deployments. |
