Activate Claim Based Authentication afterwards with PowerShell

You can active Claim Based Authentication for a SharePoint Web App afterwards if you missed that at creation time.

Use this PowerShell script:

Add-PSSnapin Microsoft.SharePoint.PowerShell -ErrorAction SilentlyContinue
[System.Reflection.Assembly]::LoadFile($Env:CommonProgramFiles+"Microsoft SharedWeb Server Extensions14ISAPIMicrosoft.SharePoint.dll") | out-null

$webapp = Get-SPWebApplication "http://<sharepoint server>/"
write-host "Current: " $webapp.UseClaimsAuthentication
$webapp.UseClaimsAuthentication = $true
$webapp.Update()

$webapp.ProvisionGlobally()

write-host "    New: " $webapp.UseClaimsAuthentication

Enable CollectSPRequestAllocationCallStacks with PowerShell

I got this message in the ULS log:

An SPRequest object was not disposed before the end of this thread. To avoid wasting system resources, dispose of this object or its parent (such as an SPSite or SPWeb) as soon as you are done using it.  This object will now be disposed.  Allocation Id: {646667A7-73BC-4DDD-B0FB-6EDFC315CCE7}  To determine where this object was allocated, set Microsoft.SharePoint.Administration.SPWebService.ContentService.CollectSPRequestAllocationCallStacks = true.

The following PowerShell script will do that for me – and you 🙂

Add-PSSnapin Microsoft.SharePoint.PowerShell -ErrorAction SilentlyContinue
[System.Reflection.Assembly]::LoadFile($Env:CommonProgramFiles+"Microsoft SharedWeb Server Extensions14ISAPIMicrosoft.SharePoint.dll") | out-null

# Get Content Service of the farm
$contentService = [Microsoft.SharePoint.Administration.SPWebService]::ContentService

# Display and change the setting of property "CollectSPRequestAllocationCallStacks"
write-host "Current: " $contentService.CollectSPRequestAllocationCallStacks 
$contentService.CollectSPRequestAllocationCallStacks = $true
$contentService.Update()

write-host "    New: " $contentService.CollectSPRequestAllocationCallStacks
