I was hoping to leave passwords out of the script for the managed accounts. I tried and gave me a
etc. meaning that the password can not be left blank.
In the functions PS1 file it is mentioned that this does not work.
#Region Add Managed Accounts
# TODO: Make this more robust, prompt for blank values etc.
As it does work with the farm password I'm still doubtful.
Can anybody confirm this behaviour is as expected from the 2.5.1. version? No prompt for Managed Accounts and have to fill them in input xml.
