Commented Feature: Add farm account to db_owner role on search databases after creation [21520]

To remedy a potential issue as written here: http://techmikael.blogspot.no/2014/10/caution-if-you-have-used.html, would it be possible to patch this using autospinstaller, granting the correct rights to the farm account?

I have not been able to reproduce it, so seems intermittant somehow. And haven't been able to get hold of all the details from Microsoft on their repro.

Could it be that for some weird case if the search service account is only in the SPSearchDBAdmins and not dbo, that this could happen. I hate issues which are hard to repro for sure. That said, it's most definitely not an AutoSPInstaller issue, but an issue with scripted installs which set's a different dbo.

I'll let you close this one for now, and I'll be sure to update if I encounter it again.
