    +## How and Why to re-authenticate withing a powershell script
    +
    +Brooklyn will run powershell scripts by making a WinRM call over HTTP. For most scripts
this will work, however for
    +some scripts (e.g. MSSQL installation), this will fail even if the script can be run
locally (e.g. by using RDP to
    +connect to the machine and running the script manually)
    +
    +In the case of MS SQL server installation, there was no clear indication of why this
would not work. The only clue was
    +a security exception in the installation log
    +
    +It appears that when a script is run over WinRM over HTTP, the credentials under which
the script are run are marked as
    +'remote' credentials, which are prohibited from running certain security-related operations.
The solution was to obtain
    +a new set of credentials within the script and use those credentials to exeute the installer,
so this:
    +
    +```
    +( $driveLetter + "setup.exe") /ConfigurationFile=C:\ConfigurationFile.ini
    +```
    +
    +became this:
    +
    +$pass = '${attribute['windows.password']}'

    Fence with ``` otherwise the formatting is mangled.
    
    (In fact, fence with ```powershell to get syntax highlighting)
