## Date

2024-06-21

## Context

**NOTE**: When configuring multiple OpenID based authentication providers on a MinIO cluster, any number of Role Policy based providers may be configured, and at most one JWT Claim based provider may be configured.

<details><summary>Example 1: Two role policy providers</summary>

Sample environment variables:

```
MINIO_IDENTITY_OPENID_DISPLAY_NAME="my first openid"

                        InetSocketAddress address,
                        RdmaProvider provider) throws IOException {
        super(context, address.getAddress(), address.getPort());
        
        this.provider = provider;
        this.rdmaConnection = provider.createConnection(address, getLocalAddress());
        this.bufferManager = new RdmaBufferManager(provider);
        this.credits = new RdmaCredits();
        

                "Method com.example.TaskInterface.getIsFailOnError(): Is not annotated with @since 2.0. Reason for accepting this: Upgraded property" to listOf("Method now provides default implementation"),
                // see https://github.com/siom79/japicmp/issues/289

        }
    }.toMap()

 * and `false` otherwise. The returned [Provider] always has a value.
