# SSO Guide (Deprecated)

## How to configure SSO

SSO require additionaly to configure TLS for application, in that example we will use self-signed certificate, in case of use legal certificates please skip step 1.

### Step 1

At this step we will generate self-signed PKCS12 keypair.

```bash
mkdir cert
keytool -genkeypair -alias ui-for-apache-kafka -keyalg RSA -keysize 2048 \
  -storetype PKCS12 -keystore cert/ui-for-apache-kafka.p12 -validity 3650
```

### Step 2

Create new application in any SSO provider, we will continue with [Auth0](https://auth0.com).

After that need to provide callback URLs, in our case we will use `https://127.0.0.1:8080/login/oauth2/code/auth0`

This is a main parameters required for enabling SSO

### Step 3

To launch Kafbat UI with enabled TLS and SSO run following:

```bash
docker run -p 8080:8080 -v `pwd`/cert:/opt/cert -e AUTH_TYPE=LOGIN_FORM \
  -e SECURITY_BASIC_ENABLED=true \
  -e SERVER_SSL_KEY_STORE_TYPE=PKCS12 \
  -e SERVER_SSL_KEY_STORE=/opt/cert/ui-for-apache-kafka.p12 \
  -e SERVER_SSL_KEY_STORE_PASSWORD=123456 \
  -e SERVER_SSL_KEY_ALIAS=ui-for-apache-kafka \
  -e SERVER_SSL_ENABLED=true \
  -e SPRING_SECURITY_OAUTH2_CLIENT_REGISTRATION_AUTH0_CLIENTID=uhvaPKIHU4ZF8Ne4B6PGvF0hWW6OcUSB \
  -e SPRING_SECURITY_OAUTH2_CLIENT_REGISTRATION_AUTH0_CLIENTSECRET=YXfRjmodifiedTujnkVr7zuW9ECCAK4TcnCio-i \
  -e SPRING_SECURITY_OAUTH2_CLIENT_PROVIDER_AUTH0_ISSUER_URI=https://dev-a63ggcut.auth0.com/ \
  -e SPRING_SECURITY_OAUTH2_CLIENT_REGISTRATION_AUTH0_SCOPE=openid \
  -e TRUST_STORE=/opt/cert/ui-for-apache-kafka.p12 \
  -e TRUST_STORE_PASSWORD=123456 \
ghcr.io/kafbat/kafka-ui
```

In the case with trusted CA-signed SSL certificate and SSL termination somewhere outside of application we can pass only SSO related environment variables:

```bash
docker run -p 8080:8080 -v `pwd`/cert:/opt/cert -e AUTH_TYPE=OAUTH2 \
  -e SPRING_SECURITY_OAUTH2_CLIENT_REGISTRATION_AUTH0_CLIENTID=uhvaPKIHU4ZF8Ne4B6PGvF0hWW6OcUSB \
  -e SPRING_SECURITY_OAUTH2_CLIENT_REGISTRATION_AUTH0_CLIENTSECRET=YXfRjmodifiedTujnkVr7zuW9ECCAK4TcnCio-i \
  -e SPRING_SECURITY_OAUTH2_CLIENT_PROVIDER_AUTH0_ISSUER_URI=https://dev-a63ggcut.auth0.com/ \
  -e SPRING_SECURITY_OAUTH2_CLIENT_REGISTRATION_AUTH0_SCOPE=openid \
ghcr.io/kafbat/kafka-ui
```

### Step 4 (Load Balancer HTTP) (optional)

If you're using load balancer/proxy and use HTTP between the proxy and the app, you might want to set `server_forward-headers-strategy` to `native` as well (`SERVER_FORWARDHEADERSSTRATEGY=native`), for more info refer to [this issue](https://github.com/kafbat/kafka-ui/issues/1017).

### Step 5 (Azure) (optional)

For Azure AD (Office365) OAUTH2 you'll want to add additional environment variables:

```bash
docker run -p 8080:8080 \
        -e KAFKA_CLUSTERS_0_NAME="${cluster_name}"\
        -e KAFKA_CLUSTERS_0_BOOTSTRAPSERVERS="${kafka_listeners}" \
        -e KAFKA_CLUSTERS_0_ZOOKEEPER="${zookeeper_servers}" \
        -e KAFKA_CLUSTERS_0_KAFKACONNECT_0_ADDRESS="${kafka_connect_servers}"
        -e AUTH_TYPE=OAUTH2 \
        -e AUTH_OAUTH2_CLIENT_AZURE_CLIENTID="xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx" \
        -e AUTH_OAUTH2_CLIENT_AZURE_CLIENTSECRET="somesecret" \
        -e AUTH_OAUTH2_CLIENT_AZURE_SCOPE="openid" \
        -e AUTH_OAUTH2_CLIENT_AZURE_CLIENTNAME="azure" \
        -e AUTH_OAUTH2_CLIENT_AZURE_PROVIDER="azure" \
        -e AUTH_OAUTH2_CLIENT_AZURE_ISSUERURI="https://login.microsoftonline.com/{tenant_id}/v2.0" \
        -e AUTH_OAUTH2_CLIENT_AZURE_JWKSETURI="https://login.microsoftonline.com/{tenant_id}/discovery/v2.0/keys" \
        -d ghcr.io/kafbat/kafka-ui"
```

Note that scope is created by default when Application registration is done in Azure portal. You'll need to update application registration manifest to include `"accessTokenAcceptedVersion": 2`
