```json
{
    "Type": "com.apple.configuration.extensible-sso",
    "Identifier": "EB13EE2B-5D63-4EBA-810F-5B81D07F5017",
    "ServerToken": "E180CA9A-F089-4FA3-BBDF-94CC159C4AE8",

        "ExtensionComposedIdentifier": "com.example.sso.extension (ABCDE12345)",
        "Type": "Credential",

        "Hosts": [
            ".example.com"
        ],
        "ExtensionData": {
            "useSiteAutoDiscovery": true
        }
    }
}
```
