It's also no error if access has been denied. Yes, sounds weird, but
keep in mind that ERROR_ACCESS_DENIED means the current user has no
permission to access the AD user information. However, if we return
an error, Cygwin will call DsGetDcName with DS_FORCE_REDISCOVERY set
to ask for another server. This is not only time consuming, it's also
useless; the next server will return access denied again. */
