PowerShell to Add FBA User to SharePoint Group and EnsureUser

function global:Add-FBAMember([parameter(mandatory=$true)][string]$siteCollUrl, [parameter(mandatory=$true)][string]$fbaUser, [parameter(mandatory=$true)][string]$spGroup)

{

# Created by Russell Wright 2015-12-21

# Updated by Russell Wright 2015-12-31 Added AllowUnsafeUpdates

# Must have machine.config <membership>, <roleManager> and <connectionStrings> sections

Add-PSSnapin microsoft.sharepoint.powershell

$web = Get-SPWeb -identity $siteCollUrl

# Save the value of AllowUnsafeUpdates

$allowUnsafeUpdates = $web.AllowUnsafeUpdates

$web.AllowUnsafeUpdates = $true

# EnsureUser initializes the user in SharePoint

$user = $web.EnsureUser($fbaUser)

$getuser = Get-SPUser -Identity $user -Web $siteCollUrl

# Set-SPUser adds the user to the SharePoint group

Set-SPUser -Identity $user -Web $siteCollUrl -Group $spGroup

$web.AllowUnsafeUpdates=$allowUnsafeUpdate

$retMsg = "Added user: " + $fbaUser + " to group " + $spGroup + " in " + $siteCollUrl

$retMsg

}

We needed a PowerShell Function to call from Winshuttle Workflow that would ensure the user was in SharePoint after a SQL load to the aspnetdb.  The trick appears to be using "AllowUnsafeUpdates," similar to what many others have posted with their C# code.  There were also some items noted in the config files where the machine.config required the FBA connection string in order for the PowerShell to work.
