Ejemplos de PowerShell y Microsoft Graph para licencias basadas en grupos de Microsoft Entra ID

La funcionalidad completa de concesión de licencias basada en grupos en Microsoft Entra ID, parte de Microsoft Entra, está disponible mediante Azure Portal. Además, en la actualidad, hay algunas tareas útiles que se pueden realizar mediante las instancias existentes de Microsoft Graph y Microsoft Graph PowerShell. Este documento proporciona ejemplos de lo que es posible.

Nota:

Antes de comenzar a ejecutar los cmdlets, asegúrese de conectarse primero a su organización con el cmdlet Connect-MgGraph.

Advertencia

Este código se proporciona como un ejemplo para fines de demostración. Si va a usarlo en su entorno, considere la posibilidad de probarlo primero a pequeña escala o en una organización de prueba independiente. Quizá deba ajustar el código para satisfacer las necesidades específicas de su entorno.

Asignación de licencias a un grupo

Use el ejemplo siguiente para asignar licencias a un grupo mediante Microsoft Graph:

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": []
}

Salida:

}

Visualización de las licencias de producto asignadas a un grupo

El cmdlet Get-MgGroup se puede usar para recuperar el objeto de grupo y comprobar la propiedad AssignedLicenses, que enumera todas las licencias de producto actualmente asignadas al grupo.

# 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

El resultado es el siguiente:

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

Nota:

Los datos devueltos aquí se limitan a la información de producto (SKU). Para generar una lista de planes de servicio deshabilitados en la licencia, consulte Ejemplos de licencias basadas en grupos de PowerShell de Microsoft Graph.

Use el siguiente ejemplo para obtener los mismos datos de Microsoft Graph.

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

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

Obtención de todos los grupos con licencias

Puede encontrar todos los grupos con cualquier licencia asignada ejecutando el comando siguiente:

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

Se pueden mostrar más detalles acerca de qué productos se han asignado:

# 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

El resultado es el siguiente:

Obtención de las estadísticas de grupos con licencias

Puede notificar estadísticas básicas para grupos con licencias. En el ejemplo siguiente, el script indica el número total de usuarios, el número de usuarios con licencias ya asignadas por el grupo y el número de usuarios para los que no se pudieron asignar licencias en el grupo.

# 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

El resultado se muestra en la tabla siguiente:

Obtención de todos los grupos con errores de licencia

Para buscar los grupos que contengan algunos usuarios para los que no se pudieron asignar licencias:

# 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

El resultado es similar al ejemplo siguiente:

GroupId                                   GroupName             TotalUserCount LicenseErrorCount

Obtención de todos los usuarios con errores de licencia en un grupo

Si un grupo contiene algunos errores relacionados con licencias, puede enumerar todos los usuarios afectados por dichos errores. Un usuario puede tener también errores de otros grupos. Sin embargo, en este ejemplo, se limitan los resultados solo a los errores relacionados con el grupo en cuestión mediante la comprobación de la propiedad ReferencedObjectId de cada entrada IndirectLicenseError del usuario.

#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}}
    }

El resultado es similar al ejemplo siguiente:

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

Obtención de todos los usuarios con errores de licencia en toda la organización

El script siguiente se puede usar para obtener todos los usuarios que tienen errores de licencia de uno o varios grupos. El script imprime una fila por cada usuario y cada error de licencia, lo que le permite identificar claramente el origen de cada error.

Nota

Este script enumera todos los usuarios de la organización que pudieran no ser óptimos para organizaciones grandes.

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
        }
    }  

El resultado es similar al ejemplo siguiente:

Aquí se muestra otra versión del script que busca únicamente en grupos que contienen errores de licencia. Puede resultar más óptimo en escenarios en los que se espera encontrar pocos grupos con problemas.

$groupIds = Get-MgGroup -All -Filter "HasMembersWithLicenseErrors eq true"
    foreach ($groupId in $groupIds) {
        $Members = Get-MgGroupMember -All -GroupId $groupId

        }
    }

Comprobación de si una licencia de usuario está asignada directamente o heredada de un grupo

Para un objeto de usuario, se puede determinar si un grupo le ha asignado una licencia de producto en particular o si se le ha asignado directamente.

Las dos funciones del ejemplo siguiente pueden utilizarse para analizar el tipo de asignación de un usuario individual:

#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
}

Este script ejecuta esas funciones en cada usuario de la organización, con el identificador de SKU como entrada; en este ejemplo estamos interesados en la licencia para Enterprise Mobility + Security, que en nuestra organización se representa con el identificador 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)}}

El resultado tiene el aspecto siguiente:

Retirada de licencias directas a usuarios con licencias de grupo

El propósito de este script es quitar las licencias directas no necesarias a los usuarios que heredan la misma licencia de un grupo; por ejemplo, como parte de una transición a licencias basadas en grupos.

Nota

Es importante validar en primer lugar que las licencias directas que va a quitar no habilitan más funcionalidades de servicio que las licencias heredadas. De lo contrario, quitar la licencia directa podría deshabilitar el acceso a servicios y datos a esos usuarios. Actualmente no es posible comprobar a través de PowerShell si los servicios se han habilitado por licencias heredadas o por licencias directas. En el script, se especifica el nivel mínimo de servicios que sabemos que se heredan de grupos y se comprobará con él para asegurarse de que los usuarios no pierdan acceso a los servicios de manera inesperada.
