Сравнение групп AD - PowerShell

Question

При использовании следующей функции (сравните членство в группе 2 пользователей) я получаю результаты, которые не имеют смысла.

function Compare-ADUserGroups <br>
{  #requires -pssnapin Quest.ActiveRoles.ADManagement  
    param (
        [string] $FirstUser = $(Throw "logonname required."),
        [string] $SecondUser = $(Throw "logonname required.")
    )

    $a = (Get-QADUser $FirstUser).MemberOf 
    $b = (Get-QADUser $SecondUser).MemberOf
    $c = Compare-Object -referenceObject $a -differenceObject $b 
    $c | Sort-Object InputObject
}

Когда я вызываю это (Compare-ADUserGroups User1 User2), я получаю набор результатов, подобный следующему:

• CN = [Все пользователи], OU = adm, DC = OSUMC, DC = EDU <= </li>
• CN = [Все пользователи], OU = adm, DC = OSUMC, DC = EDU =>
• CN = Расширенные пользователи, OU = MSG, DC = OSUMC, DC = EDU <= </li>
• CN = Расширенные пользователи, OU = MSG, DC = OSUMC, DC = EDU =>
• CN = LCS2005, OU = списки рассылки, DC = OSUMC, DC = EDU <= </li>
• CN = LCS2005, OU = Списки рассылки, DC = OSUMC, DC = EDU =>

Я ожидаю, что они не будут отображаться, учитывая, что они равны, и я не использую параметр -IncludeEqual. Любые идеи о том, почему они появляются?

Answer 1

Я пишу пользовательский интерфейс для сравнения групп и применения изменений между 2 пользователями

Answer 2

В них что-то , которое отбрасывает сравнение. Вы увидите нечто подобное, если вы запустите ...

get-process | export-clixml c \ procs.xml Diff (get-process) (import-clixml c: \ procs.xml)

Потому что НЕКОТОРЫЕ свойства этих объектов - например, такие как VM и PM, меняются в короткий интервал между двумя запусками Get-Process. Поэтому возможно, что вы сталкиваетесь с чем-то похожим, когда некоторые свойства между двумя объектами различаются. По умолчанию Compare-Object просматривает каждое свойство.

Альтернативой является использование параметра -property Compare-Object для простого сравнения определенных свойств, а не сравнение целого объекта. Compare-Object определенно может быть немного хитрым в этом отношении, потому что он работает со свойствами объекта, а не просто работает с текстом.

Answer 3

Мое лучшее предположение заключается в том, что свойство MemberOf, предоставленное Get-QADUser, вероятно, возвращает объект, а не просто различающееся имя группы в виде строки. Вот скрипт, который я использую для сравнения членства в группах Active Directory:

# Compare the group memberships of 2 Active Directory Users or the user memberships of 2 Active Directory Groups.
# Requires the ActiveDirectory PowerShell module from the Microsoft's Remote Server Administration Tools.

Import-Module ActiveDirectory

function Get-ComparisonResult ($name1, $name2, $sideIndicator)
{
    $comparisonResult = $null

    switch ($_.SideIndicator)
    {
        '<=' { $comparisonResult = "$($name1) Only" }
        '==' { $comparisonResult = "$($name1) and $($name2)" }
        '=>' { $comparisonResult = "$($name2) Only" }
    }

    return $comparisonResult
}

function Compare-ADUserGroupMembership($userName1, $userName2)
{
    $userComparisonResultColumn = @{ name = 'Comparison Result'; expression = { Get-ComparisonResult $user1.DisplayName $user2.DisplayName  $_.SideIndicator } }
    $groupNameColumn = @{ name = 'Group Name'; expression = { (Get-ADGroup $_.InputObject).Name } }

    $user1 = Get-ADUser $userName1 -Properties memberOf, displayName
    $user2 = Get-ADUser $userName2 -Properties memberOf, displayName

    $userGroupComparison = Compare-Object -IncludeEqual $user1.MemberOf $user2.MemberOf | Select $userComparisonResultColumn, $groupNameColumn

    return $userGroupComparison
}

function Compare-ADGroupMembership($groupName1, $groupName2)

    $groupComparisonResultColumn = @{ name = 'Comparison Result'; expression = { Get-ComparisonResult $groupName1 $groupName2 $_.SideIndicator } }
