Octopus Server/Tentacle service Installation wizard should offer "Service Account" as an Object Type when selecting the service account.
Currently there is no option to select a Managed Service Account object type during Octopus Server/Tentacle service installation. The work around can be found below and is fairly quick, however we should offer this during the primary installation to save time and avoid confusion.
