Microsoft Entra ID 中基于组的许可的 PowerShell 和 Microsoft Graph 示例

在属于 Microsoft Entra 的 Microsoft Entra ID 中,基于组的许可的完整功能可通过 Azure 门户获得。目前存在一些有用的任务,可以使用现有的 Microsoft Graph 和 Microsoft Graph PowerShell 执行这些任务。 本文档提供了可执行的任务示例。

注意

开始运行 cmdlet 前,请确保先通过运行 Connect-MgGraph cmdlet 来连接到组织。

警告

此示例代码用于演示目的。 如果想要在环境中使用,请考虑先进行小规模的测试,或者在单独的测试组织中测试。 可能需要根据具体的环境需求调整该代码。

将许可证分配给组

使用以下示例通过使用 Microsoft Graph 将许可证分配给组:

POST https://microsoftgraph.chinacloudapi.cn/v1.0/groups/1ad75eeb-7e5a-4367-a493-9214d90d54d0/assignLicense

      "skuId": "c7df2760-2c81-4ef7-b578-5b5392b571df"
    },
    {
      "disabledPlans": [ "a571ebcc-fqe0-4ca2-8c8c-7a284fd6c235" ],
      "skuId": "sb05e124f-c7cc-45a0-a6aa-8cf78c946968"
    }
  ],
  "removeLicenses": []
}

输出:

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

}

查看分配给组的产品许可证

Get-MgGroup cmdlet 可用于检索组对象并检查 AssignedLicenses 属性:它会列出当前分配给组的所有产品许可证。

# 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

结果如下:

SkuPartNumber
-------------
ENTERPRISEPREMIUM
EMSPREMIUM

注意

此处返回的数据被限制为产品 (SKU) 信息。 若要在许可证中生成禁用的服务计划列表,请参阅 Microsoft Graph PowerShell 组许可示例。

使用以下示例从 Microsoft Graph 获取相同的数据。

GET https://microsoftgraph.chinacloudapi.cn/v1.0/groups/99c4216a-56de-42c4-a4ac-e411cd8c7c41?$select=assignedLicenses

输出:

          "skuId":"c7df2760-2c81-4ef7-b578-5b5392b571df",
      "disabledPlans":[]
     },
     {
          "accountId":"aaaaaaaa-0000-1111-2222-bbbbbbbbbbbb",
          "skuId":" b05e124f-c7cc-45a0-a6aa-8cf78c946968",
      "disabledPlans":[]
     },
  ],
}
  ]
}

获取所有具有许可证的组

可通过运行以下命令,查找所有已分配有任意许可证的组:

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

可显示更多有关分配了哪些产品的详细信息:

# 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

结果如下:

获取具有许可证的组的统计信息

可报告具有许可证的组的基本统计信息。 在下面的示例中,脚本列出了总用户数、组已分配的具有许可证的用户数,以及组无法为其分配许可证的用户数。

# Import User Graph Module
Import-Module Microsoft.Graph.Users
# Authenticate to MS Graph
Connect-MgGraph -Environment China -ClientId 'YOUR_CLIENT_ID' -TenantId 'YOUR_TENANT_ID' -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

结果为下表:

获取含有许可证错误的所有组

查找组,这些组中包含一些无法为其分配许可证的用户:

# 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

结果与以下示例类似:

GroupId                                   GroupName             TotalUserCount LicenseErrorCount

获取组中含有许可证错误的所有用户

如果某个组中包含一些许可证相关的错误,现在可以列出受这些错误影响的所有用户。 用户也可可含有其他组中的错误。 但在此示例中,通过检查用户的每个 IndirectLicenseError 条目的 ReferencedObjectId 属性,我们仅将结果限于与所涉及组相关的错误。

#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}}
    }

结果与以下示例类似:

Id                                   DisplayName      License Error
--                                   -----------      ------------

}

获取整个组织中许可证错误的所有用户

可以使用以下脚本获取一个或多个组中具有许可证错误的所有用户。 此脚本将按每个用户、每个许可证错误输出一行,以便可以清楚地确定每个错误的源。

注意

此脚本将枚举组织中的所有用户,这对于大型组织来说可能不是最佳做法。

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
        }
    }  

结果与以下示例类似:

UserName         UserId                               GroupId                              LicenseError

下面是该脚本的另一个版本,它只在包含许可证错误的组中搜索。 预期有问题的组较少的情况下,这可能最适用。

$groupIds = Get-MgGroup -All -Filter "HasMembersWithLicenseErrors eq true"
    foreach ($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}}
        }
    }

检查用户许可证是直接从组分配还是从组继承

针对某个用户对象,可以检查某特定的产品许可证是从组分配的还是直接分配的。

以下两个示例函数可用于分析对单个用户的分配类型:

#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
}

此脚本使用 SKU ID 作为输入,对组织中的每位用户执行这些功能 - 在本示例中,用于“企业移动性 + 安全性”的许可证在组织中用 ID 表示为:contoso:EMS :

#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)}}

结果类似于以下示例:

Id                                   SkuId       AssignedDirectly AssignedFromGroup
--                                   -----       ---------------- -----------------

删除具有组许可证的用户的直接许可证

此脚本的目的是从用户(已从组继承相同许可证)删除不必要的直接许可证;例如,作为转换到基于组的许可的一部分。

注意

请务必先验证要删除的直接许可证没有比继承许可证启用更多的服务功能。 否则,删除直接许可证可能会禁用用户对服务和数据的访问。 当前无法借助 PowerShell 检查通过继承许可证与直接许可证启用了哪些服务。 在该脚本中,我们将指定要从组继承的服务的最低级别,并且将针对其进行检查,以确保用户不会意外丢失对服务的访问。

注意

在运行上述脚本之前,请根据测试环境更新变量 $skuId$groupId 的值,这些变量用于删除直接许可证。
