实现过程：在本地创建一个local user并将该user添加到Administrators组中，然后在SharePoint指定site中添加该user，并赋予Full Control的权限。
脚本如下：
function AddUserToSPSite
{
param($siteUrl,$userName,$pwd,$fullName,$dspt)
#Create a local user and add to a local group.
try{
$computer = [ADSI]"WinNT://$Env:COMPUTERNAME,Computer"
$user = $Computer.Create("User", $userName)
$user.SetPassword($pwd)
$user.SetInfo()
$user.FullName = $fullName
$user.Description = $dspt
# ADS_UF_PASSWD_CANT_CHANGE + ADS_UF_DONT_EXPIRE_PASSWD
$user.UserFlags = 64 + 65536
$user.SetInfo()
$group = [ADSI]"WinNT://./Administrators,group"
$group.Add("WinNT://$userName,user")
}catch
{
Write-Warning "User exists in local, no need to create new."
}
#Add the new created local user to a SharePoint site.
if ((Get-PSSnapin "Microsoft.SharePoint.PowerShell" -ErrorAction SilentlyContinue) -eq $null)
{
Add-PSSnapin "Microsoft.SharePoint.PowerShell"
}
$site = Get-SPSite $siteUrl
$web = $site.rootWeb
$SPUserName = $env:COMPUTERNAME+"\"+$userName
$user = New-SPUser -UserAlias $SPUserName -DisplayName $userName -Web $web
Set-SPUser -Identity $user -Web $web -AddPermissionLevel "Full Control"
}
AddUserToSPSite -siteUrl "http://xxx" -userName "xxx" -pwd "xxx" -fullName "xxx" -dspt "xxx"
如果本地已经存在欲添加的user以及成功添加user到SharePoint站点均会有提示：
