Synopsis

Removes certificate enabled/disabled extension lists.

Syntax

Remove-ExtensionList [-InputObject] <ExtensionList[]> [[-EnabledExtension] <Oid[]>] [[-OfflineExtension] <Oid[]>] [[-DisabledExtension] <Oid[]>] [<CommonParameters>]

Description

Removes certificate enabled/disabled extension lists. Extensions are sorted in 3 categories:

EnabledExtensionList - contains extensions that CA server will publish in each issued certificate upon request.

DisabledExtensionList - contains extensions that will not be published in certificate even if this extension is specified in the request.

Parameters

-InputObject <ExtensionList[]>

Specifies existing ExtensionList object. This object can be retrieved by running Get-ExtensionList command.

Required? True
Position? 0
Default value  
Accept pipeline input? true (ByValue, ByPropertyName)
Accept wildcard characters? False

-EnabledExtension <Oid[]>

Specifies the list of certificate extensions to remove that are added to the issued certificate upon request. This list is processed by policy module each time the request is resolved (produces issued certificate). You should carefully use this property and do not enable security-critical extension, like Subject Alternative Names (SAN). CA server performs additional extension processing by using '-OfflineExtension' parameter.

Required? False
Position? 1
Default value  
Accept pipeline input? false
Accept wildcard characters? False

-OfflineExtension <Oid[]>

Specifies the list of certificate extensions to remove that are added to the issued certificate against offline request. 'offline' request is such request which includes subject information and CA server do not use Active Directory to build certificate's subject. For example, requests based on default 'WebServer' certificate template are considered as 'offline', because the template is configured to build the subject from submitted request. If certificate template is configured to build the subject from Active Directory, OfflineExtensionList property has no effect and any extensions in the request are written to CA database, but not included in issued certificate.

For Standalone CAs, all requests are treated as 'offline'.

Required? False
Position? 2
Default value  
Accept pipeline input? false
Accept wildcard characters? False

-DisabledExtension <Oid[]>

Remove specified extension by it's friendly name or extension OID to prevent from publishing in issued certificates.

Required? False
Position? 3
Default value  
Accept pipeline input? false
Accept wildcard characters? False
