async function configureSSOApplication() {

    const cliInstalled = await azureCliInstalled();
    if(!cliInstalled) {

        await installAzureCli();
        console.log('Please close your command shell, reopen and run configure-sso again.  This is neccessary to register the path to the Azure CLI');
        return;
    }

    const userJson = await logIntoAzure();
    if (userJson) {
        console.log('Login was successful!');
        const manifestInfo = await manifest.readManifestFile(defaults.manifestPath);
