with an Identity Management Plugin webhook. When configured, this plugin enables the `AssumeRoleWithCustomToken` STS API extension. A user or application can now present a token to the `AssumeRoleWithCustomToken` API, and MinIO verifies this token by sending it to the Identity Management Plugin webhook. This plugin responds with some information and MinIO is able to generate temporary STS credentials to interact with object storage.

The authentication flow is similar to that of OpenID, however...

```
$ go run docs/sts/web-identity.go -cid account -csec 072e7f00-4289-469c-9ab2-bbe843c7f5a8  -config-ep "http://localhost:8080/auth/realms/minio/.well-known/openid-configuration" -port 8888
2018/12/26 17:49:36 listening on http://localhost:8888/
```

special permissions listed above. Follow [MinIO STS Quickstart Guide](https://docs.min.io/community/minio-object-store/developers/security-token-service.html) to manage users with an IDP.
