WHAT'S NEW IN DOMINO 12?
You can now allow internet certificates that contain critical extensions that are unsupported by Domino to be imported into the Domino directory or Notes personal address book.
There are some internet certificate critical extensions that Domino does not support. By default, when you attempt to import an internet certificate that has one of these extensions that is tagged as critical, the import fails with the error Unable to parse certificate.
Use the notes.ini setting ALLOW_PARSE_OF_UNSUPPORTED_CRITICAL_EXTENSIONS=1 on a server or Notes client to allow these internet certificates to be imported.
