policies to the generated credentials. MinIO's AssumeRoleWithWebIdentity implementation supports specifying IAM policies in two ways:

1. Role Policy (Recommended): When specified as part of the OpenID provider configuration, all users authenticating via this provider are authorized to (only) use the specified role policy. The policy to associate with such users is specified via the `role_policy` configuration parameter or the `MINIO_IDENTITY_OPENID_ROLE_POLICY` environment variable. The value...

### Authenticate { #authenticate }

Click the "Authorize" button.

Use the credentials:

User: `johndoe`

Password: `secret`

After authenticating in the system, you will see it like:

Now use the operation `GET` with the path `/users/me`.

## 3. Multi-Channel Architecture

### 3.1 Channel States
```java
public enum ChannelState {
    DISCONNECTED(0),     // Not connected
    CONNECTING(1),       // Connection in progress
    AUTHENTICATING(2),   // Authentication in progress
    ESTABLISHED(3),      // Ready for use
    BINDING(4),         // Channel binding in progress
    ACTIVE(5),          // Actively transferring data

search_engine.http.url=http://localhost:9201
# Path to SSL certificate authorities for secure HTTP connections.
search_engine.http.ssl.certificate_authorities=
# Username for authenticating to the search engine.
search_engine.username=
# Password for authenticating to the search engine.
search_engine.password=
# Interval (ms) for heartbeat checks to the search engine.
search_engine.heartbeat_interval=10000

 *  Fix: Improve recovery from failed routes.
 *  Fix: Accommodate tunneling proxies that close the connection after an auth
    challenge.
 *  Fix: Use the proxy authenticator when authenticating HTTP proxies. This
    regression was introduced in OkHttp 3.0.
 *  Fix: Fail fast if network interceptors transform the response body such that
    closing it doesn't also close the underlying stream. We had a bug where
