Total Auth Timeout

This setting is the maximum total time in seconds to spend searching and authorizing results, during Results Authorization. The maximum setting value is -1 for no limit, i.e. let Search Timeout (here) cancel the search if reached. Any other negative value is relative to Search Timeout. Thus the default (if empty) of -5 means stop searching 5 seconds before Search Timeout, so that there are a few seconds left to send the results to the user.
