Directory extension attributes allow you to extend the schema of Azure AD objects with custom attributes that can be synchronized from on-premises Active Directory. This function supports two parameter sets: specifying individual properties or providing a complete attribute string. It includes validation and conflict resolution capabilities. This function requires Windows PowerShell 5.1 and does not work with PowerShell 7. .PARAMETER Name Specifies the name of the directory extension attribute to add. The name should be unique within the object class and follow Azure AD naming conventions. .PARAMETER Type Specifies the data type of the directory extension attribute. Common types include: - String: Text data - Integer: Numeric data - Boolean: True/False values - DateTime: Date and time values .PARAMETER AssignedObjectClass Specifies the object class to which this attribute will be assigned. Common values include: - user: For user objects - group: For group objects - contact: For contact objects - device: For device objects .PARAMETER IsEnabled Specifies whether the directory extension attribute is enabled for synchronization. Set to $true to enable or $false to disable. .PARAMETER FullAttributeString Specifies a complete attribute definition string in the format: "attributeName.objectClass.dataType.enabledStatus" For example: "employeeNumber.user.String.True" .PARAMETER Force Forces the addition of the attribute even if a conflicting attribute with the same name but different type exists. When specified, the existing conflicting attribute is removed. .EXAMPLE Add-AADConnectDirectoryExtensionAttribute -Name "employeeNumber" -Type "String" -AssignedObjectClass "user" -IsEnabled $true Adds an employee number attribute for user objects as a string type. .EXAMPLE Add-AADConnectDirectoryExtensionAttribute -FullAttributeString "departmentCode.user.String.True" Adds a department code attribute using the full attribute string format. .EXAMPLE Add-AADConnectDirectoryExtensionAttribute -Name "badgeNumber" -Type "Integer" -AssignedObjectClass "user" -IsEnabled $true -Force Adds a badge number attribute, replacing any existing conflicting attribute with the same name. .EXAMPLE Get-Content "attributes.txt" | ForEach-Object { Add-AADConnectDirectoryExtensionAttribute -FullAttributeString $_ } Adds multiple attributes from a text file, with each line containing a full attribute string. .INPUTS String. You can pipe attribute strings to this function when using the FullAttributeString parameter. .OUTPUTS None.

This utility function is commonly used in DSC configurations and Azure AD Connect management scenarios where hashtable representations of objects are needed for parameter passing or configuration storage. The function filters out properties with null values to create a clean hashtable with only meaningful data. This is particularly useful when working with Azure AD Connect objects that may have many optional properties.

You can pipe any PowerShell object to Convert-ObjectToHashtable. .OUTPUTS Hashtable. Returns a hashtable containing all non-null properties and their values. .NOTES - This function works with both Windows PowerShell 5.1 and PowerShell 7 - Properties with null values are excluded from the resulting hashtable - Complex nested objects are included as-is (not recursively converted) - The function is optimized for performance and memory efficiency - Useful for DSC configurations and Azure AD Connect object manipulation .LINK https://docs.microsoft.com/en-us/powershell/scripting/learn/deep-dives/everything-about-hashtable .COMPONENT AADConnectDsc .FUNCTIONALITY PowerShell Object Utilities #> function Convert-ObjectToHashtable { [OutputType([hashtable])] param ( [Parameter(Mandatory = $true, ValueFromPipeline = $true)] [object]$Object ) process { $hashtable = @{ } foreach ($property in $Object.PSObject.Properties.Where({ $null -ne $_.Value })) { $hashtable.Add($property.Name, $property.Value) } $hashtable } } #EndRegion '.\Public\Convert-ObjectToHashtable.ps1' 93 #Region '.\Public\Get-AADConnectDirectoryExtensionAttribute.ps1' -1 <# .SYNOPSIS Retrieves directory extension attributes from Azure AD Connect configuration. .DESCRIPTION The Get-AADConnectDirectoryExtensionAttribute function retrieves directory extension attributes that are currently configured in Azure AD Connect global settings.

Must match exactly with the existing attribute's object class (user, group, contact, device, etc.). .PARAMETER FullAttributeString Specifies a complete attribute definition string in the format: "attributeName.objectClass.dataType.enabledStatus" For example: "employeeNumber.user.String.True" .EXAMPLE Remove-AADConnectDirectoryExtensionAttribute -Name "employeeNumber" -Type "String" -AssignedObjectClass "user" Removes the employee number directory extension attribute for user objects. .EXAMPLE Remove-AADConnectDirectoryExtensionAttribute -FullAttributeString "departmentCode.user.String.True" Removes the department code directory extension attribute using the full attribute string format. .EXAMPLE Get-AADConnectDirectoryExtensionAttribute -Name "obsolete*" | Remove-AADConnectDirectoryExtensionAttribute Removes all directory extension attributes with names starting with "obsolete". .EXAMPLE $attribute = Get-AADConnectDirectoryExtensionAttribute -Name "tempAttribute" if ($attribute) { Remove-AADConnectDirectoryExtensionAttribute -Name $attribute.Name -Type $attribute.Type -AssignedObjectClass $attribute.AssignedObjectClass } Safely removes a directory extension attribute after verifying it exists. .INPUTS PSCustomObject. You can pipe directory extension attribute objects from Get-AADConnectDirectoryExtensionAttribute. .OUTPUTS None. This function does not return objects but modifies Azure AD Connect global settings. .NOTES - This function requires Windows PowerShell 5.1 and does not work with PowerShell 7 - Requires Azure AD Connect to be installed and the ADSync module to be available - Changes take effect immediately but may require synchronization cycle restart - Verify that the attribute is not used in synchronization rules before removal - Use Get-AADConnectDirectoryExtensionAttribute to verify the attribute was removed successfully - Removed attributes cannot be recovered; back up configuration before making changes .LINK https://docs.microsoft.com/en-us/azure/active-directory/hybrid/how-to-connect-sync-feature-directory-extensions .COMPONENT AADConnectDsc .FUNCTIONALITY Azure AD Connect Directory Extension Attribute Management #> function Remove-AADConnectDirectoryExtensionAttribute { [CmdletBinding(DefaultParameterSetName = 'ByProperties')] param ( [Parameter(Mandatory = $true, ValueFromPipelineByPropertyName = $true, ParameterSetName = 'ByProperties')] [string]$Name, [Parameter(Mandatory = $true, ValueFromPipelineByPropertyName = $true, ParameterSetName = 'ByProperties')] [string]$Type, [Parameter(Mandatory = $true, ValueFromPipelineByPropertyName = $true, ParameterSetName = 'ByProperties')] [string]$AssignedObjectClass, [Parameter(Mandatory = $true, ParameterSetName = 'SingleObject')] $FullAttributeString ) process { $currentAttributes = Get-AADConnectDirectoryExtensionAttribute if ($FullAttributeString) { $attributeValues = $FullAttributeString -split '\.' if ($attributeValues.Count -ne 4) { Write-Error "The attribute string did not have the correct format.
