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 checked another AutoSPInstaller-built farm and on it, the Farm Account isn't a db_owner on the Search databases. However, it's part of a DB role called __SPSearchDBAdmin__, which FWIW has been granted Alter and Execute on the stored procedure you mention in your post (proc_MSS_GetConfigurationProperty).

I also read elsewhere (in an other issue, that could be related: https://autospinstaller.codeplex.com/workitem/21167) that this role gets dropped and re-created regularly (not sure why). So maybe in your case, the role was dropped, but something prevented it from getting re-created?
