NAME Revoke-ADAuthenticationPolicySiloAccess



SYNOPSIS

Revokes membership in an authentication policy silo for the specified account.





SYNTAX

Revoke-ADAuthenticationPolicySiloAccess [-Identity] <ADAuthenticationPolicySilo> [-Account] <ADAccount> [-AuthType

{Negotiate | Basic}] [-Credential <PSCredential>] [-PassThru] [-Server <String>] [-Confirm] [-WhatIf]

[<CommonParameters>]





DESCRIPTION

The Revoke-ADAuthenticationPolicySiloAccess cmdlet revokes the membership in an authentication policy silo for one

or more accounts in Active Directory???? Domain Services.



The Identity parameter specifies the Active Directory Domain Services authentication policy silo that contains the

user accounts to remove. You can identify an authentication policy silo by its distinguished name (DN), GUID or

name. You can also use the Identity parameter to specify a variable that contains an authentication policy silo

object, or you can use the pipeline operator to pass an authentication policy object to the Identity parameter.



The Account parameter specifies the users, computers and service accounts to remove from the authentication policy

silo specified by the Identity parameter. You can identify a user, computer or service account by its DN, GUID,

security identifier (SID), or Security Accounts Manager (SAM) account name. You can also use the Account parameter

to specify a variable that contains user, computer, and service account objects.





PARAMETERS

-Account <ADAccount>

Specifies the account to remove from the authentication policy silo. Specify the account in one of the

following formats:



-- Distinguished Name



-- GUID



-- Security Identifier



-- SAM Account Name



The cmdlet searches the default naming context or partition to find the object. If two or more objects are

found, the cmdlet returns a non-terminating error.



You can also use this parameter to specify a variable that contains user, computer, and service account

objects.



Required? true

Position? 1

Default value

Accept pipeline input? True (ByValue)

Accept wildcard characters? false



-AuthType <ADAuthType>

Specifies the authentication method to use. The acceptable values for this parameter are:??



--Negotiate or 0



--Basic or 1



The default authentication method is Negotiate. A Secure Sockets Layer (SSL) connection is required for the

Basic authentication method.



Required? false

Position? named

Default value Microsoft.ActiveDirectory.Management.AuthType.Negotiate

Accept pipeline input? false

Accept wildcard characters? false



-Credential <PSCredential>

Specifies a user account that has permission to perform the task. The default is the current user. Type a user

name, such as "User01" or "Domain01\\User01", or enter a PSCredential object, such as one generated by the

Get-Credential cmdlet.



By default, the cmdlet uses the credentials of the currently logged on user unless the cmdlet is run from an

Active Directory Domain ServicesWindows PowerShell provider drive. If you run the cmdlet in a provider drive,

the account associated with the drive is the default.



If you specify credentials that do not have permission to perform the task, the cmdlet returns an error.



Required? false

Position? named

Default value

Accept pipeline input? false

Accept wildcard characters? false



-Identity <ADAuthenticationPolicySilo>

Specifies an ADAuthenticationPolicySilo object. Specify the authentication policy silo object in one of the

following formats:



--Distinguished Name



--GUID



--Name



This parameter can also get this object through the pipeline or you can set this parameter to an object

instance.



The cmdlet searches the default naming context or partition to find the object. If the cmdlet finds two or

more objects, the cmdlet returns a non-terminating error.



Required? true

Position? 0

Default value

Accept pipeline input? false

Accept wildcard characters? false



-PassThru [<SwitchParameter>]

Returns an object representing the item with which you are working. By default, this cmdlet does not generate

any output.



Required? false

Position? named

Default value

Accept pipeline input? false

Accept wildcard characters? false



-Server <String>

Specifies the Active Directory Domain Services instance to which to connect, by providing one of the following

values for a corresponding domain name or directory server. The service may be any of the following: Active

Directory Lightweight Domain Services, Active Directory Domain Services or Active Directory Snapshot instance.



Specify the Active Directory Domain Services instance in one of the following ways:



--Domain name values:



----Fully qualified domain name



----NetBIOS name



--Directory server values:



----Fully qualified directory server name



----NetBIOS name



----Fully qualified directory server name and port



The default value for this parameter is determined by one of the following methods in the order that they are

listed:



--By using the Server value from objects passed through the pipeline



--By using the server information associated with the Active Directory Domain ServicesWindows PowerShell

provider drive, when the cmdlet runs in that drive



--By using the domain of the computer running Windows PowerShell



Required? false

Position? named

Default value

Accept pipeline input? false

Accept wildcard characters? false



-Confirm [<SwitchParameter>]

Prompts you for confirmation before running the cmdlet.



Required? false

Position? named

Default value false

Accept pipeline input? false

Accept wildcard characters? false



-WhatIf [<SwitchParameter>]

Shows what would happen if the cmdlet runs. The cmdlet is not run.



Required? false

Position? named

Default value false

Accept pipeline input? false

Accept wildcard characters? false



<CommonParameters>

This cmdlet supports the common parameters: Verbose, Debug,

ErrorAction, ErrorVariable, WarningAction, WarningVariable,

OutBuffer, PipelineVariable, and OutVariable. For more information, see

about_CommonParameters (http://go.microsoft.com/fwlink/?LinkID=113216).



INPUTS

None or Microsoft.ActiveDirectory.Management.ADAuthenticationPolicySilo



This cmdlet accepts an authentication policy silo object.





OUTPUTS

None or Microsoft.ActiveDirectory.Management.ADAuthenticationPolicySilo



This cmdlet returns the modified authentication policy silo object when the PassThru parameter is specified.

By default, this cmdlet does not generate any output.





Example 1: Revoke access to an authentication policy silo



PS C:\\>Revoke-ADAuthenticationPolicySiloAccess ????????Identity AuthenticationPolicySilo01 ????????Account User01 ????????Confirm:$False



This command revokes access to the authentication policy silo named AuthenticationPolicySilo01 for the user

account named User01. Because the Confirm parameter is set to $False, no confirmation message appears.

Example 2: Revoke access to an authentication policy silo for filter matches



PS C:\\>Get-ADComputer -Filter 'Name -like "newComputer*"' | Revoke-ADAuthenticationPolicySiloAccess -Identity

AuthenticationPolicySilo02



Confirm



Are you sure you want to perform this action?



Performing the operation "Set" on target "CN=Silo,CN=AuthN Silos,CN=AuthN Policy

Configuration,CN=Services,CN=Configuration,DC=DC01,DC=Contoso,DC=com".



[Y] Yes [A] Yes to All [N] No [L] No to All [S] Suspend [?] Help (default is "Y"): A



This example first uses the Get-ADComputer cmdlet to get a list of computers that match the filter specified by

the Filter parameter. The output is then passed to the Revoke-ADAuthenticationPolicySiloAccess to remove access to

the authentication policy silo named AuthenticationPolicySilo02. Because the Confirm parameter is not specified, a

confirmation message appears.
