How do I set the OSearch14 Service Account via PowerShell

Question

I'm in the process of Scripting a deployment of SharePoint 2010 and FAST.

Normally to set the Service Account of a SharePoint service one would use the ProcessIdentity property, like so:

$procId = (Get-SPSearchService).ProcessIdentity
$procId.CurrentIdentityType = "SpecificUser"
$procId.ManagedAccount = $myManagedAcount
$procId.Update()

This works a treat for the SearchService object returned by Get-SPSearchService, however the SearchService object returned by Get-SPEnterpriseSearchService has an additional ScriptProperty that hides the ProcessIdentity property, and returns it as a string, rather than an SPProcessIdentity, which can't be updated.

So, The question: Can I remove this ScriptProperty? OR Can I change the service account via PowerShell without access to the ProcessIdentity Property?

Answer 1

You Need to Set the Managed Account Information and then Deploy for it to take affect.

$myManagedAccount = Get-SpManagedAccount -Identity "<Name of Account Here>"
$procId = (Get-SPEnterpriseSearchService).get_ProcessIdentity()
$procId.CurrentIdentityType = "SpecificUser"
$procId.ManagedAccount = $myManagedAcount
$procId.Update()
$procID.Deply()

Then this can be done after the Service has started :-)

Answer 2

You should use .Deploy() after .Update()

Answer 3

Seems to be tricky

according to this article :

there appear to be missing one key piece: setting the default content access account to some service account other than the SharePoint farm account.
