### Step 3. Update istioctl schema

Istioctl uses a [schema](../../operator/pkg/apis/values_types.proto) to validate the values. Any changes to
the schema must be added here, otherwise istioctl users will see errors.
Once the schema file is updated, run:

```bash
$ make operator-proto
```

This will regenerate the Go structs used for schema validation.

### Step 4. Update the generated manifests

   * specified is included. To create a copy of a {@code SortedSet} that preserves the comparator,
   * call {@link #copyOfSorted} instead. This method iterates over {@code elements} at most once.
   *
   * <p>Note that if {@code s} is a {@code Set<String>}, then {@code ImmutableSortedSet.copyOf(s)}
   * returns an {@code ImmutableSortedSet<String>} containing each of the strings in {@code s},

   * returns a {@link SortedSet}, instead of the {@link java.util.Collection} specified in the
   * {@link Multimap} interface.
   *
   * <p>Any duplicates in {@code values} will be stored in the multimap once.

- JAVA 1.8 and above installed already and JAVA_HOME points to JAVA 1.8 installation.
- Download WSO2 follow their [installation guide](https://docs.wso2.com/display/IS540/Installation+Guide).

### 2. Configure WSO2

Once WSO2 is up and running, configure WSO2 to generate Self contained id_tokens. In OAuth 2.0 specification there are primarily two ways to provide id_tokens
