function Invoke-FMSchemaLdif { <# .SYNOPSIS Applies missing LDIF files to a forest's schema. .DESCRIPTION Applies missing LDIF files to a forest's schema. .PARAMETER InputObject Test results provided by the associated test command. Only the provided changes will be executed, unless none were specified, in which ALL pending changes will be executed. .PARAMETER Server The server / domain to work with. .PARAMETER Credential The credentials to use for this operation. .PARAMETER EnableException This parameters disables user-friendly warnings and enables the throwing of exceptions. This is less user friendly, but allows catching exceptions in calling scripts. .PARAMETER Confirm If this switch is enabled, you will be prompted for confirmation before executing any operations that change state. .PARAMETER WhatIf If this switch is enabled, no actions are performed but informational messages will be displayed that explain what would happen if the command were to run. .EXAMPLE PS C:\> Invoke-FMSchemaLdif Tests the configured LDIF schema files and applies all still missing updates. #> [CmdletBinding(SupportsShouldProcess = $true, ConfirmImpact = 'Low')] Param ( [Parameter(ValueFromPipeline = $true)] $InputObject, [PSFComputer] $Server, [PSCredential] $Credential, [switch] $EnableException ) begin { #region Resolve Schema Master $parameters = $PSBoundParameters | ConvertTo-PSFHashtable -Include Server, Credential $parameters['Debug'] = $false Assert-ADConnection @parameters -Cmdlet $PSCmdlet Invoke-Callback @parameters -Cmdlet $PSCmdlet Assert-Configuration -Type SchemaLdif -Cmdlet $PSCmdlet Set-FMDomainContext @parameters try { $forest = Get-ADForest @parameters -ErrorAction Stop } catch { Stop-PSFFunction -String 'Invoke-FMSchemaLdif.Connect.Failed' -StringValues $Server -ErrorRecord $_ -EnableException $EnableException -Exception $_.Exception.GetBaseException() return } $parameters["Server"] = $forest.SchemaMaster $removeParameters = $parameters.Clone() #endregion Resolve Schema Master #region Resolve Credentials $cred = $null if (Test-SchemaAdminCredential) { Invoke-PSFProtectedCommand -ActionString 'Invoke-FMSchemaLdif.Schema.Credentials' -Target $forest.SchemaMaster -ScriptBlock { [PSCredential]$cred = Get-SchemaAdminCredential @parameters | Write-Output | Select-Object -First 1 if ($cred) { $parameters['Credential'] = $cred } } -EnableException $EnableException.ToBool() -PSCmdlet $PSCmdlet if (Test-PSFFunctionInterrupt) { return } } #endregion Resolve Credentials # Prepare parameters to use for when discarding the schema credentials if ($cred -and ($cred -ne $Credential)) { $removeParameters['SchemaAccountCredential'] = $cred } } process { if (Test-PSFFunctionInterrupt) { return } if (-not $InputObject) { $InputObject = Test-FMSchemaLdif @parameters -EnableException:$EnableException } foreach ($testItem in $InputObject) { Invoke-PSFProtectedCommand -ActionString 'Invoke-FMSchemaLdif.Invoke.File' -ActionStringValues $testItem.Identity -Target $forest.SchemaMaster -ScriptBlock { Invoke-LdifFile @parameters -Path $testItem.Configuration.Path -ErrorAction Stop } -EnableException $EnableException.ToBool() -PSCmdlet $PSCmdlet -Continue } } end { if (Test-PSFFunctionInterrupt) { return } if (Test-SchemaAdminCredential) { Invoke-PSFProtectedCommand -ActionString 'Invoke-FMSchemaLdif.Schema.Credentials.Release' -Target $forest.SchemaMaster -ScriptBlock { Remove-SchemaAdminCredential @removeParameters -ErrorAction Stop } -EnableException $EnableException -PSCmdlet $PSCmdlet } } } |
