[otrs] Simple Support Assessment question

I just installed the 2.4.6 update, and then ran the Support Assessment. It had "Apache:DBI" marked as critical (although I know at some point in the past this was OK... or I'm completely daft... or both :-) Anyway, I found that in scripts/apache2-perl-startup.pl the "use Apache:DBI" was commented out. I simply uncommented that single line and restarted apache. All was well, and the Assessment now gives "OK" for the Apache::DBI check. However, since I supplied no credentials or anything, this seemed too easy, so I'm wondering: * Does the Support Assessment just look to see if the Apache:DBI command is in the scripts... or can it actually determine somehow that it's functioning properly? Thanks, Mike
