net` to ensure the browser receives a valid reachable URL. Similarly, if your TLS certificates do not have the IP SAN for the MinIO server host, the MinIO Console may fail to validate the connection to the server. Use the `MINIO_SERVER_URL` environment variable and specify the proxy-accessible hostname of the MinIO server to allow the Console to use the MinIO server API using the TLS certificate. For example: `export MINIO_SERVER_URL="https://minio.example.net"` | Dashboard | Creating a bucket |...

### Configure MinIO server with Dex

```
~ export MINIO_IDENTITY_OPENID_CLAIM_NAME=name
~ export MINIO_IDENTITY_OPENID_CONFIG_URL=http://127.0.0.1:5556/dex/.well-known/openid-configuration
~ minio server ~/test
```

### Run the `web-identity.go`

```
~ go run web-identity.go -cid example-app -csec ZXhhbXBsZS1hcHAtc2VjcmV0 \

```

## 4. Install Certificates from Third-party CAs

MinIO can connect to other servers, including MinIO nodes or other server types such as NATs and Redis. If these servers use certificates that were not registered with a known CA, add trust for these certificates to MinIO Server by placing these certificates under one of the following MinIO configuration paths:

* **Linux:** `~/.minio/certs/CAs/`

## Duplicate headers { #duplicate-headers }

It is possible to receive duplicate headers. That means, the same header with multiple values.

	defer func() {
		globalMinioHost, globalMinioPort = prevHost, prevPort
	}()
	// tg[0] = local, tg[1] = remote

	// Remote URL
	url, err := xnet.ParseHTTPURL(tg.Servers[1].URL)
	if err != nil {
		t.Fatalf("unexpected error %v", err)
	}
	url.Path = t.TempDir()

	globalMinioHost, globalMinioPort = mustSplitHostPort(url.Host)

To test this setup, access the MinIO server via browser or [`mc`](https://docs.min.io/community/minio-object-store/reference/minio-mc.html#quickstart). You’ll see the uploaded files are accessible from the all the MinIO endpoints.
