* Updated in $/Perl/OlleDB
* Also except the settings for Trust Server Certificate and Host Name in
* Certificate when setting the provider string.
*
* ***************** Version 16 *****************
* User: Sommar Date: 22-05-27 Time: 21:59
* Updated in $/Perl/OlleDB
* The correction of the one-off error was in the wrong place. When
* setting provider string, don't clear the Encrypt setting, because for
* some reason it does not have any effect when you list it in the
* provider string. When comparing property IDs, also include the propset
* as some properties have the same ids.
*
* ***************** Version 15 *****************
* User: Sommar Date: 22-05-18 Time: 22:23
* Updated in $/Perl/OlleDB
* Added validation of the values of the Authentication propery. If
* AccessToken is given, clear IntegratedSecurity.
