// permissions changed from 744 to 755.
// The reason is that if user 'A' does a restore then user 'A' will be the only
// user allowed to start or stop a domain. Whether or not a user is allowed to start a domain
// needs to be based on the AppServer authentication mechanism (username-password) rather
// than on the OS authentication mechanism.
// This case actually is common: user 'A' does the restore, root tries to start the restored domain.
