Microsoft Entra 識別符中群組型授權的 PowerShell 和 Microsoft Graph 範例

Microsoft Entra 標識符中群組型授權的完整功能可透過 Azure 入口網站 取得,目前有一些實用的工作可以使用現有的 Microsoft Graph 和 Microsoft Graph PowerShell 來執行。 本檔提供可能的範例。

注意

開始執行 Cmdlet 之前,請先執行 連線-MgGraph Cmdlet,確定先連線到您的組織。

警告

此程式代碼是示範用途的範例。 如果您想要在環境中使用它,請考慮先在小規模或個別的測試組織中進行測試。 您可能需要調整程序代碼,以符合環境的特定需求。

指派授權至群組

使用下列範例,使用 Microsoft Graph 將授權指派給群組:

POST https://graph.microsoft.com/v1.0/groups/1ad75eeb-7e5a-4367-a493-9214d90d54d0/assignLicense
Content-type: application/json
{
  "addLicenses": [
    {
      "disabledPlans": [ "11b0131d-43c8-4bbb-b2c8-e80f9a50834a" ],
      "skuId": "c7df2760-2c81-4ef7-b578-5b5392b571df"
    },
    {
      "disabledPlans": [ "a571ebcc-fqe0-4ca2-8c8c-7a284fd6c235" ],
      "skuId": "sb05e124f-c7cc-45a0-a6aa-8cf78c946968"
    }
  ],
  "removeLicenses": []
}

輸出:

  "deletedDateTime": null,
  "classification": null,
  "createdDateTime": "2018-04-18T22:05:03Z",
  "securityEnabled": true,

}

檢視指派給群組的產品授權

Get-MgGroup Cmdlet 可用來擷取群組物件並檢查 AssignedLicenses 屬性:它會列出目前指派給群組的所有產品授權。

# Define the group ID
$groupId = "99c4216a-56de-42c4-a4ac-e411cd8c7c41"

# Get the group with the specified ID and its assigned licenses
$group = Get-MgGroup -GroupId $groupId -Property "AssignedLicenses"

# Extract the assigned licenses
$assignedLicenses = $group | Select-Object -ExpandProperty AssignedLicenses

# Extract the SKU IDs from the assigned licenses
$skuIds = $assignedLicenses | Select-Object -ExpandProperty SkuId

# For each SKU ID, get the corresponding SKU part number
$skuPartNumbers = $skuIds | ForEach-Object {
    $skuId = $_
    $subscribedSku = Get-MgSubscribedSku | Where-Object { $_.SkuId -eq $skuId }
    $skuPartNumber = $subscribedSku | Select-Object -ExpandProperty SkuPartNumber
    $skuPartNumber
}

# Output the SKU part numbers
$skuPartNumbers

以下是結果:

SkuPartNumber

ENTERPRISEPREMIUM
EMSPREMIUM

注意

此處重新微調的數據僅限於產品 (SKU) 資訊。 若要在授權中產生已停用的服務方案清單,請參閱 群組授權的 Microsoft Graph PowerShell 範例。

使用下列範例從 Microsoft Graph 取得相同的數據。

GET https://graph.microsoft.com/v1.0/groups/99c4216a-56de-42c4-a4ac-e411cd8c7c41?$select=assignedLicenses

輸出:

      "disabledPlans":[]
     },
  ],
}
  ]
}

取得具有授權的所有群組

您可以執行下列命令,找到所有具有任何授權的群組:

Get-MgGroup -All -Property Id, MailNickname, DisplayName, GroupTypes, Description, AssignedLicenses | Where-Object {$_.AssignedLicenses -ne $null }

更多詳細資料可以顯示哪些產品已指派:

# Get all groups with assigned licenses
$groups = Get-MgGroup -All -Property Id, MailNickname, DisplayName, GroupTypes, Description, AssignedLicenses | Where-Object {$_.AssignedLicenses -ne $null }

# Process each group
$groupInfo = foreach ($group in $groups) {
    # For each group, get the SKU part numbers of the assigned licenses
    $skuPartNumbers = foreach ($skuId in $group.AssignedLicenses.SkuId) {
        $subscribedSku = Get-MgSubscribedSku | Where-Object { $_.SkuId -eq $skuId }
        $subscribedSku.SkuPartNumber
    }

    # Create a custom object with the group's object ID, display name, and license SKU part numbers
    [PSCustomObject]@{
        ObjectId = $group.Id
        DisplayName = $group.DisplayName
        Licenses = $skuPartNumbers -join ', '
    }
}

$groupInfo

以下是結果:

取得具有授權之群組的統計數據

您可以報告具有授權之群組的基本統計數據。 在下列範例中,腳本會列出用戶總數、群組已指派授權的用戶計數,以及群組無法指派授權的用戶計數。

# Import User Graph Module
Import-Module Microsoft.Graph.Users
# Authenticate to MS Graph
Connect-MgGraph -Scopes "User.Read.All", "Directory.Read.All", "Group.ReadWrite.All"
#get all groups with licenses
$groups = Get-MgGroup -All -Property LicenseProcessingState, DisplayName, Id, AssignedLicenses | Select-Object  displayname, Id, LicenseProcessingState, AssignedLicenses | Select-Object DisplayName, Id, AssignedLicenses -ExpandProperty LicenseProcessingState | Select-Object DisplayName, State, Id, AssignedLicenses | Where-Object {$_.State -eq "ProcessingComplete"}
$groupInfoArray = @()
# Filter the groups to only include those that have licenses assigned
$groups = $groups | Where-Object {$_.AssignedLicenses -ne $null}
# For each group, get the group name, license types, total user count, licensed user count, and license error count
foreach ($group in $groups) {
    $groupInfo = New-Object PSObject
    $groupInfo | Add-Member -MemberType NoteProperty -Name "Group Name" -Value $group.DisplayName
    $groupInfo | Add-Member -MemberType NoteProperty -Name "Group ID" -Value $group.Id
    $groupInfo | Add-Member -MemberType NoteProperty -Name "License Types" -Value ($group.AssignedLicenses | Select-Object -ExpandProperty SkuId)
    $groupInfo | Add-Member -MemberType NoteProperty -Name "Total User Count" -Value (Get-MgGroupMember -GroupId $group.Id -All | Measure-Object).Count
    $groupInfo | Add-Member -MemberType NoteProperty -Name "Licensed User Count" -Value (Get-MgGroupMember -GroupId $group.Id -All | Where-Object {$_.      LicenseProcessingState -eq "ProcessingComplete"} | Measure-Object).Count
    $groupInfo | Add-Member -MemberType NoteProperty -Name "License Error Count" -Value (Get-MgGroupMember -GroupId $group.Id -All | Where-Object {$_.LicenseProcessingState -eq "ProcessingFailed"} | Measure-Object).Count
    $groupInfoArray += $groupInfo
}

# Format the output and print it to the console
$groupInfoArray | Format-Table -AutoSize

結果如下表:

取得所有具有授權錯誤的群組

若要尋找包含某些使用者無法指派授權的群組:

# Get all groups that have assigned licenses
$groups = Get-MgGroup -All -Property DisplayName, Id, AssignedLicenses | 
    Where-Object { $_.AssignedLicenses -ne $null } | 
    Select-Object DisplayName, Id, AssignedLicenses

# Initialize an array to store group information
$groupInfo = @()

# Iterate over each group
foreach ($group in $groups) {
    $groupId = $group.Id
    $groupName = $group.DisplayName

    # Initialize counters for total members and members with license errors
    $totalCount = 0
    $licenseErrorCount = 0

    # Get all members of the group that have license errors
    $members = Get-MgGroupMemberWithLicenseError -GroupId $groupId

    # Process each member
    foreach ($member in $members) {
        $totalCount++

        # If the member has a license error (indicated by a non-empty Id), increment the error count
        if (![string]::IsNullOrEmpty($member.Id)) {
            $licenseErrorCount++
        }
    }

    # Create a custom object with the group's information and counts
    $groupInfo += [PSCustomObject]@{
        GroupName         = $groupName
        GroupId           = $groupId
        TotalUserCount    = $totalCount
        LicenseErrorCount = $licenseErrorCount
    }
}

# Display the groups with licensing errors
$groupInfo | Where-Object { $_.LicenseErrorCount -gt 0 } | Format-Table -Property GroupName, GroupId, TotalUserCount, LicenseErrorCount

結果看起來像下列範例:

取得群組中發生授權錯誤的所有使用者

指定包含某些授權相關錯誤的群組,您現在可以列出受這些錯誤影響的所有使用者。 使用者也可以有來自其他群組的錯誤。 不過,在此範例中,我們只會檢查使用者上每個 IndirectLicenseError 專案的 ReferencedObjectId 屬性,將結果限製為與有問題的群組相關的錯誤。

#a sample group with errors
$groupId = '11151866-5419-4d93-9141-0603bbf78b42'

#get all user members of the group
$Members = Get-MgGroupMember -All -GroupId $groupId 
#get full information about user objects
Foreach ($Member in $Members) {
    Get-MgUser -UserId $Member.Id |
        #filter out users without license errors and users with license errors from other groups
        Where {$Member.AdditionalProperties.IndirectLicenseErrors -and $Member.AdditionalProperties.IndirectLicenseErrors.ReferencedObjectId -eq $groupId} |
        #display id, name and error detail. Note: we are filtering out license errors from other groups
        Select Id, `
            DisplayName, `
            @{Name="LicenseError";Expression={$Member.AdditionalProperties.IndirectLicenseErrors | 
            Where {$Member.AdditionalProperties.IndirectLicenseErrors.ReferencedObjectId -eq $groupId} | 
            Select -ExpandProperty Error}}
    }

結果看起來像下列範例:

}

取得整個組織中發生授權錯誤的所有使用者

下列腳本可用來取得來自一或多個群組之授權錯誤的所有使用者。 腳本會為每個使用者列印一個數據列,每個授權錯誤,這可讓您清楚識別每個錯誤的來源。

注意

此腳本會列舉組織中所有使用者,這可能不適合大型組織。

Get-MgUser -All | Where {$_.AdditionalProperties.IndirectLicenseErrors } | % {   
    $user = $_;
    $user.AdditionalProperties.IndirectLicenseErrors | % {
        New-Object Object |
        Add-Member -NotePropertyName UserName -NotePropertyValue $user.DisplayName -PassThru |
        Add-Member -NotePropertyName UserId -NotePropertyValue $user.Id -PassThru |
        Add-Member -NotePropertyName GroupId -NotePropertyValue $_.AdditionalProperties.IndirectLicenseErrors.ReferencedObjectId -PassThru |
        Add-Member -NotePropertyName LicenseError -NotePropertyValue $_.AdditionalProperties.IndirectLicenseErrors -PassThru
        }

以下是另一個版本的腳本,只會搜尋包含授權錯誤的群組。 它可能更針對您預期有少數問題群組的案例進行優化。

$groupIds = Get-MgGroup -All -Filter "HasMembersWithLicenseErrors eq true"
    foreach ($groupId in $groupIds) {
        $Members = Get-MgGroupMember -All -GroupId $groupId 
        foreach ($Member in $Members) { Get-Get-MgUser -UserId $Member.Id |
            Where {$Member.AdditionalProperties.IndirectLicenseErrors -and $Member.AdditionalProperties.IndirectLicenseErrors.ReferencedObjectId -eq $groupId.ObjectID} |
            Select DisplayName, `
                   ObjectId, `
                   @{Name="LicenseError";Expression={$Member.AdditionalProperties.IndirectLicenseErrors | Where {$Member.AdditionalProperties.IndirectLicenseErrors.ReferencedObjectId -eq $groupId.Id} | Select -ExpandProperty Error}}
        }
    }

檢查用戶授權是否已直接指派或繼承自群組

針對用戶物件,可以檢查特定產品授權是否已從群組指派,或是否已直接指派。

下列兩個範例函式可用來分析個別使用者的指派類型:

#Returns TRUE if the user has the license assigned directly
function UserHasLicenseAssignedDirectly
{
    Param([Microsoft.Graph.PowerShell.Models.IMicrosoftGraphUser]$user, [string]$skuId)

    foreach($license in $user.Licenses)
    {
        #we look for the specific license SKU in all licenses assigned to the user
        if ($license.AccountSkuId -ieq $skuId)
        {
            #GroupsAssigningLicense contains a collection of IDs of objects assigning the license
            #This could be a group object or a user object (contrary to what the name suggests)
            #If the collection is empty, this means the license is assigned directly - this is the case for users who have never been licensed via groups in the past
            if ($license.GroupsAssigningLicense.Count -eq 0)
            {
                return $true
            }

            #If the collection contains the ID of the user object, this means the license is assigned directly
            #Note: the license may also be assigned through one or more groups in addition to being assigned directly
            foreach ($assignmentSource in $license.GroupsAssigningLicense)
            {
                if ($assignmentSource -ieq $user.ObjectId)
                {
                    return $true
                }
            }
            return $false
        }
    }
    return $false
}
#Returns TRUE if the user is inheriting the license from a group
function UserHasLicenseAssignedFromGroup
{
    Param([Microsoft.Graph.PowerShell.Models.IMicrosoftGraphUser]$user, [string]$skuId)

    foreach($license in $user.Licenses)
    {
        #we look for the specific license SKU in all licenses assigned to the user
        if ($license.AccountSkuId -ieq $skuId)
        {
            #GroupsAssigningLicense contains a collection of IDs of objects assigning the license
            #This could be a group object or a user object (contrary to what the name suggests)
            foreach ($assignmentSource in $license.GroupsAssigningLicense)
            {
                #If the collection contains at least one ID not matching the user ID this means that the license is inherited from a group.
                #Note: the license may also be assigned directly in addition to being inherited
                if ($assignmentSource -ine $user.ObjectId)
                {
                    return $true
                }
            }
            return $false
        }
    }
    return $false
}

此腳本會使用 SKU 標識符做為輸入,在組織中執行這些函式-在此範例中,我們對 Enterprise Mobility + Security授權感興趣,此授權會以標識符 contoso:EMS 表示:

#the license SKU we are interested in. use Get-MgSubscribedSku to see a list of all identifiers in your organization
$skuId = "contoso:EMS"

#find all users that have the SKU license assigned
Get-MgUser -All | where {$_.isLicensed -eq $true -and $_.Licenses.AccountSKUID -eq $skuId} | select `
    Id, `
    @{Name="SkuId";Expression={$skuId}}, `
    @{Name="AssignedDirectly";Expression={(UserHasLicenseAssignedDirectly $_ $skuId)}}, `
    @{Name="AssignedFromGroup";Expression={(UserHasLicenseAssignedFromGroup $_ $skuId)}}

結果看起來像下列範例:

拿掉具有群組授權的使用者直接授權

此腳本的目的是要從已經從群組繼承相同授權的使用者移除不必要的直接授權;例如,作為轉換至群組型授權的一部分。

注意

請務必先驗證要移除的直接授權不會啟用比繼承的授權更多的服務功能。 否則,移除直接授權可能會停用使用者對服務和數據的存取。 目前無法透過PowerShell檢查透過繼承授權與直接啟用的服務。 在腳本中,我們會指定我們所知道的最小服務層級是繼承自群組,並檢查該層級,以確保使用者不會意外失去服務的存取權。
