goscim

SCIM server written in Go

This is one lite implementation of SCIM 2.0 (http://www.simplecloud.info/)

Overview

The System for Cross-domain Identity Management (SCIM) specification is designed to make managing user identities in cloud-based applications and services easier. The specification suite seeks to build upon experience with existing schemas and deployments, placing specific emphasis on simplicity of development and integration, while applying existing authentication, authorization, and privacy models. Its intent is to reduce the cost and complexity of user management operations by providing a common user schema and extension model, as well as binding documents to provide patterns for exchanging this schema using standard protocols. In essence: make it fast, cheap, and easy to move users in to, out of, and around the cloud. (cut and past :P )

TODO

  • Bulk operation
  • Improve PATH

Run

For run you need one sever couchbase (https://www.couchbase.com/)

Run docker couchbase

docker run -d --name db -p 8091-8094:8091-8094 -p 11210:11210 couchbase
  • Go to http://localhost:8091/ui/index.html
  • If you need config only click in "Setup New Cluster"
  • Complete "Cluster Name", "Create Admin Username" and "Create Password" and click "Next: Accept Terms"
  • Example
    • "Cluster Name" -> cluster_scim
    • "Create Admin Username" -> Administrator
    • "Create Password" -> admin!
  • Check "I accept the terms & conditions" and click "Finish With Defaults"

Set env

export SCIM_ADMIN_USER=Administrator
export SCIM_ADMIN_PASSWORD=admin!

You can set SCIM_COUCHBASE_URL but the default value is localhost. You can set SCIM_PORT but the default value is :8080.

Run Scim Server

go run .

Test http

I used REST Client https://github.com/Huachao/vscode-restclient

Schemas

The schemas is location in config/schemas and you can modify them and add new schemas. Remember that one new schema need one resourceType. The ResourceType is location in config/resourceType

Example User (urn:ietf:params:scim:schemas:extension:enterprise:2.0:User)

Resource Type User.json

{
  "schemas": ["urn:ietf:params:scim:schemas:core:2.0:ResourceType"],
