# Overview

This tutorial shows how to configure Keycloak as an authentication method for HashiCorp Vault.

## Prerequisites

- Keycloak server - https://keycloak.server.com
- Custom certificate for Keycloak server - https://github.com/myreposotory/blob/main/keycloak/tls.crt
- Realm name for Keycloak server - "example"
- HashiCorp Vault server - https://vault.server.com

## Steps

1. Log in to the Vault server using the root token.

```sh
vault login root
```

2. Enable the Keycloak authentication method.

```sh
vault auth enable keycloak
```

[Command reference](https://developer.hashicorp.com/vault/docs/commands/auth/enable)

3. Configure the Keycloak authentication method.

```sh
vault write auth/keycloak/config \
    oidc_discovery_url="https://keycloak.server.com/auth/realms/master/.well-known/openid-configuration" \
    default_role="oidc-role" \
    tls_client_cert_pem=@/path/to/custom-certificate.pem \
    tls_client_key_pem=@/path/to/custom-certificate-key.pem
```

4. Create a role that maps a user in Keycloak to a set of Vault policies.

```sh
vault write auth/keycloak/role/oidc-role \
    bound_realm="mcsp" \
    user_claim="preferred_username" \
    groups_claim="groups" \
    policies="vault-policy"
```

## Validation

1. Log in to the Keycloak server using a user account that belongs to the mcsp realm.
2. Access the Vault UI at https://vault.server.com/ui and click on the Tokens tab.
3. Click on the Create Token button and select the vault-policy policy from the list of policies.
4. Click on the Create Token button to generate a new token.
5. Copy the generated token and log in to the Vault server using the token.

```sh
vault login <generated-token>
```

6. Verify that the login was successful by checking the output of the vault status command.

```sh
vault status
```
