function Resolve-SchemaAttribute { <# .SYNOPSIS Combines configuration and adobject into an attributes hashtable. .DESCRIPTION Combines configuration and adobject into an attributes hashtable. This is a helper function that allows to simplify the code used to create and update schema attributes. .PARAMETER Configuration The configuration object containing the desired schema attribute name. .PARAMETER ADObject The ADObject - if present - containing the current schema attribute configuration. Specifying this will cause it to return a delta hashtable useful for updating attributes. .PARAMETER Changes Changes to be applied to an existing attribute. .EXAMPLE PS C:\> Resolve-SchemaAttribute -Configuration $testItem.Configuration Returns the attributes hashtable for a new schema attribute. .EXAMPLE PS C:\> Resolve-SchemaAttribute -Configuration $testItem.Configuration -ADObject $testItem.ADObject Returns the attributes hashtable for attributes to update. #> [OutputType([hashtable])] [CmdletBinding()] param ( $Configuration, $ADObject, $Changes ) begin { function Convert-AttributeName { [OutputType([string])] [CmdletBinding()] param ( [Parameter(ValueFromPipeline = $true)] [AllowEmptyCollection()] [AllowEmptyString()] [AllowNull()] [string[]] $Name ) process { foreach ($entry in $Name) { if ($null -eq $entry) { continue } switch ($entry) { SingleValued { 'isSingleValued' } OID { 'attributeID' } PartialAttributeSet { 'isMemberOfPartialAttributeSet' } AdvancedView { 'showInAdvancedViewOnly' } default { $_ } } } } } } process { #region Build out basic attribute hashtable $attributes = @{ adminDisplayName = $Configuration.AdminDisplayName lDAPDisplayName = $Configuration.LdapDisplayName attributeId = $Configuration.OID oMSyntax = $Configuration.OMSyntax attributeSyntax = $Configuration.AttributeSyntax isSingleValued = ($Configuration.SingleValued -as [bool]) adminDescription = $Configuration.AdminDescription searchflags = $Configuration.SearchFlags isMemberOfPartialAttributeSet = $Configuration.PartialAttributeSet showInAdvancedViewOnly = $Configuration.AdvancedView } #endregion Build out basic attribute hashtable #region Case: New Attribute if (-not $ADObject) { $badProperties = foreach ($pair in $attributes.GetEnumerator()) { if ($null -eq $pair.Value) { $pair.Key } } if ($null -eq $Configuration.SingleValued) { $badProperties = @($badProperties) + @('SingleValued') } if ($badProperties) { throw "Cannot create new attribute $($Configuration.AdminDisplayName), missing attributes: $($badProperties -join ',')" } return $attributes } #endregion Case: New Attribute #region Case: Update Settings $updates = @{ } foreach ($change in $Changes) { $updates[($change.Property | Convert-AttributeName)] = $change.New } $systemOnly = @( 'isSingleValued' 'oMSyntax' 'attributeId' 'attributeSyntax' ) foreach ($attributeName in ($updates.Keys | Write-Output)) { if ($systemOnly -contains $attributeName) { Write-PSFMessage -Level Warning -String 'Resolve-SchemaAttribute.Update.SystemOnlyError' -StringValues $attributeName, $attributes.$attributeName, $ADObject $attributes.Remove($attributeName) } } #endregion Case: Update Settings $attributes } } |
