# Casdoor Quickstart Guide [](https://slack.min.io)
|
|
|
|
Casdoor is a UI-first centralized authentication / Single-Sign-On (SSO) platform supporting OAuth 2.0, OIDC and SAML, integrated with Casbin RBAC and ABAC permission management. This document covers configuring Casdoor identity provider support with MinIO.
|
|
|
|
## Prerequisites
|
|
|
|
Configure and install casdoor server by following [Casdoor Server Installation](https://casdoor.org/docs/basic/server-installation).
|
|
For a quick installation, docker-compose reference configs are also available on the [Casdoor Try with Docker](https://casdoor.org/docs/basic/try-with-docker).
|
|
|
|
### Configure Casdoor
|
|
|
|
- Go to Applications
|
|
- Create or use an existing Casdoor application
|
|
- Edit the application
|
|
- Copy `Client ID` and `Client secret`
|
|
- Add your redirect url (callback url) to `Redirect URLs`
|
|
- Save
|
|
|
|
- Go to Users
|
|
- Edit the user
|
|
- Add your MinIO policy (ex: `readwrite`) in `Tag`
|
|
- Save
|
|
|
|
- Open your favorite browser and visit: **http://`CASDOOR_ENDPOINT`/.well-known/openid-configuration**, you will see the OIDC configure of Casdoor.
|
|
|
|
### Configure MinIO
|
|
|
|
```
|
|
export MINIO_ROOT_USER=minio
|
|
export MINIO_ROOT_PASSWORD=minio123
|
|
minio server /mnt/export
|
|
```
|
|
|
|
Here are all the available options to configure OpenID connect
|
|
|
|
```
|
|
mc admin config set myminio/ identity_openid
|
|
|
|
KEY:
|
|
identity_openid enable OpenID SSO support
|
|
|
|
ARGS:
|
|
config_url* (url) openid discovery document e.g. "https://accounts.google.com/.well-known/openid-configuration"
|
|
client_id (string) unique public identifier for apps e.g. "292085223830.apps.googleusercontent.com"
|
|
claim_name (string) JWT canned policy claim name, defaults to "policy"
|
|
claim_prefix (string) JWT claim namespace prefix e.g. "customer1/"
|
|
scopes (csv) Comma separated list of OpenID scopes for server, defaults to advertised scopes from discovery document e.g. "email,admin"
|
|
comment (sentence) optionally add a comment to this setting
|
|
```
|
|
|
|
and ENV based options
|
|
|
|
```
|
|
mc admin config set myminio/ identity_openid --env
|
|
|
|
KEY:
|
|
identity_openid enable OpenID SSO support
|
|
|
|
ARGS:
|
|
MINIO_IDENTITY_OPENID_CONFIG_URL* (url) openid discovery document e.g. "https://accounts.google.com/.well-known/openid-configuration"
|
|
MINIO_IDENTITY_OPENID_CLIENT_ID (string) unique public identifier for apps e.g. "292085223830.apps.googleusercontent.com"
|
|
MINIO_IDENTITY_OPENID_CLAIM_NAME (string) JWT canned policy claim name, defaults to "policy"
|
|
MINIO_IDENTITY_OPENID_CLAIM_PREFIX (string) JWT claim namespace prefix e.g. "customer1/"
|
|
MINIO_IDENTITY_OPENID_SCOPES (csv) Comma separated list of OpenID scopes for server, defaults to advertised scopes from discovery document e.g. "email,admin"
|
|
MINIO_IDENTITY_OPENID_COMMENT (sentence) optionally add a comment to this setting
|
|
```
|
|
|
|
Set `identity_openid` config with `config_url`, `client_id` and restart MinIO
|
|
|
|
```
|
|
~ mc admin config set myminio identity_openid config_url="http://CASDOOR_ENDPOINT/.well-known/openid-configuration" client_id=<client id> client_secret=<client secret> claim_name="tag"
|
|
```
|
|
|
|
> NOTE: As MinIO needs to use a claim attribute in JWT for its policy, you should configure it in casdoor as well. Currently, casdoor uses `tag` as a workaround for configuring MinIO's policy.
|
|
|
|
Once successfully set restart the MinIO instance.
|
|
|
|
```
|
|
mc admin service restart myminio
|
|
```
|
|
|
|
### Using WebIdentiy API
|
|
|
|
On another terminal run `web-identity.go` a sample client application which obtains JWT id_tokens from an identity provider, in our case its Keycloak. Uses the returned id_token response to get new temporary credentials from the MinIO server using the STS API call `AssumeRoleWithWebIdentity`.
|
|
|
|
```
|
|
$ go run docs/sts/web-identity.go -cid account -csec 072e7f00-4289-469c-9ab2-bbe843c7f5a8 -config-ep "http://CASDOOR_ENDPOINT/.well-known/openid-configuration" -port 8888
|
|
2018/12/26 17:49:36 listening on http://localhost:8888/
|
|
```
|
|
|
|
This will open the login page of Casdoor, upon successful login, STS credentials along with any buckets discovered using the credentials will be printed on the screen, for example:
|
|
|
|
```
|
|
{
|
|
buckets: [ ],
|
|
credentials: {
|
|
AccessKeyID: "EJOLVY3K3G4BF37YD1A0",
|
|
SecretAccessKey: "1b+w8LlDqMQOquKxIlZ2ggP+bgE51iwNG7SUVPJJ",
|

### Using MinIO Console
|
|
|
|
- Open MinIO URL on the browser, lets say <http://localhost:9000/>
|
|
- Click on `Login with SSO`
|
|
- User will be redirected to the Casdoor user login page, upon successful login the user will be redirected to MinIO page and logged in automatically,
|
|
the user should see now the buckets and objects they have access to.
