When editing Authentication Settings in MMC under NetScaler Gateway applicance, the Auth type is reverted to Domain. For instance, if we select Smartcard then apply the changes and reopen the console, the authtype would appear as "Domain". However, the configuration file will make the changes. Only the MMC does not reflect the changes.
