scim2-server

This is an example WSGI-SCIM server using scim2-models. It utilizes werkzeug and scim2-filter-parser and keeps all resources in-memory, they are lost once the process exits.

Features

• Discovery endpoints (/v2/ServiceProviderConfig, /v2/ResourceTypes, /v2/Schemas)
• Create/Read/Update/Delete resources (POST, GET, PUT, DELETE)
• Searching & Filtering
• Support for ETags
• Unique Constraints
• HTTP PATCH (Add/Remove/Replace)
• Sorting

The only optional feature currently missing is support for Bulk operations (RFC 7644, Section 3.7).

Usage

$ scim2-server [-h] [--schema SCHEMA] [--resource-type RESOURCE_TYPE] [--bearer-token BEARER_TOKEN] [--hostname HOSTNAME] [--port PORT] [--reverse-proxy] [--dump-resources DUMP_RESOURCES]

• -h/--help: Show help message
• --reverse-proxy: Allow using the provider behind a Reverse Proxy (required for URL rewriting).
• --schema: Register schemas from specified JSON file. If not provided, loads the default schemas from RFC 7643.
• --resource-type: Register resource types from specified JSON file. If not provided, loads the default resource types from RFC 7643.
• --bearer-token: Registers a bearer token that can be used for accessing the service. If no tokens are provided, anonymous access without authentication is allowed.
• --hostname: The hostname to listen on. Defaults to 127.0.0.1.
• --port: The port to listen on. Defaults to 8080.
• --dump-resources: Dump a JSON document containing all resources when the provider exits normally.

Notes

This provider can be used as a starting point if you want to implement a SCIM provider. You should probably change the following things, if you want to use it in production:

• Use a proper production WSGI server instead of the one provided by Werkzeug
• Implement your own Backend as a subclass of scim2_server.backend.Backend
• Implement proper authorization with OAuth instead of public access or static bearer tokens
• Support the /Me endpoint, if it applies in your use case
• Add support for using either a static URL prefix or improve the support for usage behind a reverse proxy

The provider in its current state has been tested successfully against a live Microsoft Entra system as well as a live Okta system.
