Enumeration of All Users in a Group (traversing nested groups) in Active Directory

As a counter part to my previous post, I created a dual of the script which enumerates Groups and their members.

#
#    Enumerate All Users for a Group (including traversing nested groups) 
#        @param distinguishedName - The distinguished name of the object you want to traverse
#    Brock Moeller
#    12/16/2009
#
param (
    $distinguishedName = "CN=SuperGroup,OU=Groups,DC=serv,DC=ubercorp,DC=com"
)
 
$roles = @{};
$indent = -1;
filter EnumMember {
    $indent += 1;
    if ($_ -is [System.DirectoryServices.DirectoryEntry]){
        $adsiObj = $_;
    } else {
        $adsiObj = New-Object System.DirectoryServices.DirectoryEntry("LDAP://" + $_);
    }
    if ((-not [String]::IsNullOrEmpty($adsiObj.cn)) -and (-not $roles.ContainsKey($adsiObj.cn))){
        $roles[$adsiObj.cn] = 1;
        $memberOfCount = $adsiObj.member.Count;
        $("`t"*$indent) + $adsiObj.cn + " [$memberOfCount]";
        if (($memberOfCount -gt 0) -and ($indent -lt 900)) {
            $adsiObj.member | EnumRoles;
        }
    }
    $indent -= 1;
}
 
$user = [adsi]"LDAP://$distinguishedName";
$user;
$buffer = $user.Path + "`n";
$user | EnumMember | % { $buffer += $_ + "`n" };
"Buffer: " + $buffer.ToString();
[System.IO.File]::WriteAllText("$pwd\$($user.cn).txt", $buffer.ToString());

Enumeration of All Groups for a User (traversing nested groups) in Active Directory

I ran into an odd situation where I needed to be able to enumerate all of the groups that a user was a member. I found a lot of programs and scripts that will list the groups for a user, but none that would traverse nested groups.

The script writes the information to a file for better reviewing later. The output adds indentation to help readability.

Here is my solution.

#
#    Enumerate All Groups for a User (including traversing nested groups) 
#        @param distinguishedName - The distinguished name of the object you want to traverse
#        Brock Moeller
#        12/16/2009
#
param (
    $distinguishedName = "CN=Joe Dirt,OU=Users,DC=serv,DC=ubercorp,DC=com"
)
 
$roles = @{};
$indent = -1;
filter EnumRoles {
    $indent += 1;
    if ($_ -is [System.DirectoryServices.DirectoryEntry]){
        $adsiObj = $_;
    } else {
        $adsiObj = New-Object System.DirectoryServices.DirectoryEntry("LDAP://" + $_);
    }
    if ((-not [String]::IsNullOrEmpty($adsiObj.cn)) -and (-not $roles.ContainsKey($adsiObj.cn))){
        $roles[$adsiObj.cn] = 1;
        $memberOfCount = $adsiObj.memberOf.Count;
        $("`t"*$indent) + $adsiObj.cn + " [$memberOfCount]";
        if (($memberOfCount -gt 0) -and ($indent -lt 900)) {
            $adsiObj.memberOf | EnumRoles;
        }
    }
    $indent -= 1;
}
 
$user = [adsi]"LDAP://$distinguishedName";
$user;
$buffer = $user.Path + "`n";
$user | EnumRoles | % { $buffer += $_ + "`n" };
"Buffer: " + $buffer.ToString();
[System.IO.File]::WriteAllText("$pwd\$($user.cn).txt", $buffer.ToString());

Google Reader Grease Monkey Script

I was bored one day and decided that I wanted to fix up the Google Reader interface a little bit and this was the result. Sure there are more useful GM scripts, but this is a start.

// ==UserScript==
// @name           Google Reader Fixup
// @namespace      http://intellectualponderings.blogspot.com

function getElementPosition(element) {
    var pos = {x:0, y:0};
    if (element.offsetParent) {
        while (element.offsetParent) {
            pos.x += element.offsetLeft;
            pos.y += element.offsetTop;
            element = element.offsetParent;
        }
    } else if (element.x) {
        pos.x += element.x;
        pos.y += element.y;
    }
    return pos; 
}
 
function InfoMouseClick(e) {
    var gei = document.getElementById,

        entriesStatus.style.right = "0.5em";

    }
    entries.style.height = String(d.documentElement.clientHeight - getElementPosition(entries).y - footer.offsetHeight) + "px";
}
 
(function () {

    googbutton.innerHTML=buttonStr;
    chrome.appendChild(googbutton);
    googbutton.addEventListener('click', InfoMouseClick, false); 
})();
