Get App Pool Identity for IIS in Power Shell Script

Question

Trying to get Application Pool Identity in IIS for a specific name, for example : Test

Succeded in getting it via below code but dont want to loop through all the webapps, is there any easy of getting it by specifying the name?

Import-Module WebAdministration
Get-WebApplication

$webapps = Get-WebApplication
$list = @()
foreach ($webapp in get-childitem IIS:\AppPools\)
{
    $name = "IIS:\AppPools\" + $webapp.name
    $item = @{}
    if ($webapp.name -eq 'Test')
    {        
        $item = $webapp.processModel.identityType   
        break
    }
}


echo $webapp.processModel.identityType

Answer 1

Not strictly what the OP wanted, but google led me here for querying all App Pool Identities. This is my version

Import-Module WebAdministration;Get-ChildItem -Path IIS:\AppPools\ | 
Select-Object name, state, managedRuntimeVersion, managedPipelineMode, @{e={$_.processModel.username};l="username"}, <#@{e={$_.processModel.password};l="password"}, #> @{e={$_.processModel.identityType};l="identityType"} |
format-table -AutoSize

Needed this but none of the answers had complete code so I put something together.

Try {
    Import-Module WebAdministration -ErrorAction Stop
} Catch {
    Write-Error -Message "Unable to load required module."
}

$webapps = Get-ChildItem –Path IIS:\AppPools
$list = [System.Collections.ArrayList]::new()
foreach ($webapp in $webapps) {
    $Pool = "IIS:\AppPools\" + $webapp.name
    $sid = New-Object System.Security.Principal.SecurityIdentifier (
        Get-Item $Pool | select -ExpandProperty applicationPoolSid
    )
    [void]$List.add([PSCustomObject]@{
        Name = $webapp.name
        Pool = $Pool
        ServiceAccount = $sid.Translate([System.Security.Principal.NTAccount])
    })
}
$list

Output

Name              Pool                            ServiceAccount               
----              ----                            --------------               
.NET v4.5         IIS:\AppPools\.NET v4.5         IIS APPPOOL\.NET v4.5        
.NET v4.5 Classic IIS:\AppPools\.NET v4.5 Classic IIS APPPOOL\.NET v4.5 Classic
DefaultAppPool    IIS:\AppPools\DefaultAppPool    IIS APPPOOL\DefaultAppPool   
WsusPool          IIS:\AppPools\WsusPool          IIS APPPOOL\WsusPool

Just combine the path and retrieve the item. This will work:

$item = Get-Item (Join-Path 'IIS:\AppPools\' 'Test') | 
   select -ExpandProperty processModel | 
   select -expand identityType
