Unregister-ObjectIdentifier

Unregister-ObjectIdentifier

Synopsis

Unregisters object identifier (OID) information from local computer, Active Directory or both sources.

Syntax

Unregister-ObjectIdentifier [-Value] <Oid2> [-UseActiveDirectory] [-Force] [-WhatIf] [-Confirm] [<CommonParameters>]

Description

Unregisters object identifier (OID) information from local computer, Active Directory or both sources. Additionally, the command accepts pipeline input from the following commands: Get-ObjectIdentifier and Get-ObjectIdentifierEx.

In order the command to succeed the caller must be granted with:
1) local administrator permissions — if an OID is registered locally.
2) Enterprise Admins permissions, or delegated Write permissions on OID container in Active Directory, if 'UseActiveDirectory' switch is enabled.

OID container in Active Directory is located under: CN=Public Key Services, CN=Services, <Configuration Naming Context>.

Parameters

-Value <Oid2>

Specifies an OID friendly name, value or System.Security.Cryptography.Oid2 object that contains information about OID to unregister. Only specified instance is unregistered. By default, the command attempts to unregister specified OID information from local machine only. In order to unregister OID information in Active Directory, use 'UseActiveDirectory' switch.
