Let me start this off by saying I’m new to PowerShell AND I’m sure someone could sum up my code in one line of code.

I was asked to provide a list of all users in a SharePoint Site Collection / Web App. The person asking this, was wanting to see each user, the site and list they had access to. More or less I needed to iterate through all the sites, loop on the user, loop again on the site, then loop on the lists.

So the layout I could provide was:

Site Collection
User Name
Site
List

I’m outputting the results to a file name UserAccess.txt on the C:\ drive.

[System.Reflection.Assembly]::Load(“Microsoft.SharePoint, Version=12.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c”)
[System.Reflection.Assembly]::Load(“Microsoft.SharePoint.Portal, Version=12.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c”)

$spsite=[Microsoft.SharePoint.SPSite]("http://sharepoint/")

out-file c:\UserAccess.txt -append

foreach ($Site in $spsite.AllWebs)
{
    "Site Collection Name:  $Site" | out-file c:\UserAccess.txt -append
    foreach ($User in $Site.SiteUsers)
    {
        "--User Name: $User" | out-file c:\UserAccess.txt -append
        foreach ($Site in $spsite.AllWebs)
        {
					$SitePermissions = $Site.Permissions
					foreach($mySitePermission in $SitePermissions)
					{
						if($User.ID -eq $mySitePermission.Member.ID)
						{
                            "----Site Name: $Site" | out-file c:\UserAccess.txt -append
						}
					}

                    foreach($myList in $Site.lists)
        			{

        					$myListPermissions = $myList.Permissions
        					foreach($myListPermission in $myListPermissions)
        					{
        						if($User.ID -eq $myListPermission.Member.ID)
        						{
                                    "------List Name: $MyList" | out-file c:\UserAccess.txt -append
        						}
        					}
        			}

                 $Site.Dispose()
			}
            $Site.Dispose()
        }
    }
