Description

The Add-ADDomainControllerPasswordReplicationPolicy cmdlet adds one or more users, computers, and groups to the allowed or denied list of a read-only domain controller (RODC) password replication policy.

The Identity parameter specifies the read-only domain controller (RODC) that uses the allowed and denied lists to apply the password replication policy. You can identify a domain controller by its GUID, IPV4Address, global IPV6Address, or DNS host name. You can also identify a domain controller by the name of the server object that represents the domain controller, the distinguished name of the NTDS settings object of the server object, the GUID of the NTDS settings object of the server object under the configuration partition, or the distinguished name of the computer object that represents the domain controller. You can also set the Identity parameter to a domain controller object variable, such as $<localDomainControllerObject>, or pass a domain controller object through the pipeline to the Identity parameter. For example, you can use the Get-ADDomainController cmdlet to get a domain controller object and then pass the object through the pipeline to the Add-ADDomainControllerPasswordReplicationPolicy cmdlet. You must specify a read-only domain controller. If you specify a writeable domain controller for this parameter, the cmdlet returns a non-terminating error.

The AllowedList parameter specifies the users, computers, and groups to add to the allowed list. Similarly, the DeniedList parameter specifies the users, computers, and groups to add to the denied list. You must specify either one or both of the AllowedList and DeniedList parameters. You can identify a user, computer, or group by distinguished name, GUID, security identifier (SID) or Security Accounts Manager (SAM) account name. You can also specify user, computer, or group variables, such as $<localUserObject>. If you are specifying more than one item, use a comma-separated list. If a specified user, computer, or group is not on the allowed or denied list, the cmdlet does not return an error.

Examples

Example 1

$params = @{
    Identity = 'USER01-RODC1'
    AllowedList = 'PattiFuller', 'DavidChew'
}
Add-ADDomainControllerPasswordReplicationPolicy @params

This command adds user accounts with the specified SamAccountNames to the Allowed list on the RODC specified by the Identity parameter.

Example 2

$params = @{
    Identity = 'USER02-RODC1'
    DeniedList = 'ElisaDaugherty', 'EvanNarvaez'
}
Add-ADDomainControllerPasswordReplicationPolicy @params

This command adds user accounts with the specified SamAccountNames to the Denied list on the RODC specified by the Identity parameter.

Parameters

-AllowedList

Specifies the users, computers, groups or other accounts to add to the list of accounts allowed to replicate their passwords to this RODC. You can specify more than one value by using a comma-separated list. The acceptable values for this parameter are:

• A distinguished name
• A GUID (objectGUID)
• A security identifier (objectSid)
• A Security Accounts Manager (SAM) account name (sAMAccountName)

Type:	ADPrincipal[]
Position:	Named
Default value:	None
Required:	True
Accept pipeline input:	False
Accept wildcard characters:	False

-AuthType

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.

Type:	ADAuthType
Accepted values:	Negotiate, Basic
Position:	Named
Default value:	None
Required:	False
Accept pipeline input:	False
Accept wildcard characters:	False

-Confirm

Prompts you for confirmation before running the cmdlet.

Type:	SwitchParameter
Aliases:	cf
Position:	Named
Default value:	False
Required:	False
Accept pipeline input:	False
Accept wildcard characters:	False

-Credential

Specifies the user account credentials to use to perform this task. The default credentials are the credentials of the currently logged on user unless the cmdlet is run from an Active Directory module for Windows PowerShell provider drive. If the cmdlet is run from such a provider drive, the account associated with the drive is the default.

To specify this parameter, you can type a user name, such as User1 or Domain01\User01 or you can specify a PSCredential object. If you specify a user name for this parameter, the cmdlet prompts for a password.

You can also create a PSCredential object by using a script or by using the Get-Credential cmdlet. You can then set the Credential parameter to the PSCredential object.

If the acting credentials do not have directory-level permission to perform the task, Active Directory module for Windows PowerShell returns a terminating error.

Type:	PSCredential
Position:	Named
Default value:	None
Required:	False
Accept pipeline input:	False
Accept wildcard characters:	False

-DeniedList

Specifies the users, computers, groups or other accounts to add to the list of accounts that are denied the right to replicate their passwords to this RODC. You can specify more than one value by using a comma-separated list. The acceptable values for this parameter are:

• A distinguished name
• A GUID (objectGUID)
• A security identifier (objectSid)
• A Security Accounts Manager (SAM) account name (sAMAccountName)

Type:	ADPrincipal[]
Position:	Named
Default value:	None
Required:	True
Accept pipeline input:	False
Accept wildcard characters:	False

-Identity

Specifies an Active Directory domain controller object by providing one of the following values. The identifier in parentheses is the Lightweight Directory Access Protocol (LDAP) display name for the attribute. The acceptable values for this parameter are:

• A GUID (objectGUID)
• An IPV4Address
• A Global IPV6Address
• A DNS Host Name (dNSHostName)
• A name of the server object
• A distinguished name of the NTDS Settings object
• A distinguished name of the server object that represents the domain controller
• A GUID of NTDS settings object under the configuration partition
• A GUID of server object under the configuration partition
• A distinguished name of the computer object that represents the domain controller

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.

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

Type:	ADDomainController
Position:	0
Default value:	None
Required:	False
Accept pipeline input:	False
Accept wildcard characters:	False

-Server

Specifies the Active Directory Domain Services instance to connect to, 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 Services Windows PowerShell provider drive, when the cmdlet runs in that drive
• By using the domain of the computer running Windows PowerShell

Type:	String
Position:	Named
Default value:	None
Required:	False
Accept pipeline input:	False
Accept wildcard characters:	False

-WhatIf

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

Type:	SwitchParameter
Aliases:	wi
Position:	Named
Default value:	False
Required:	False
Accept pipeline input:	False
Accept wildcard characters:	False

Inputs

ADDomainController

An RODC object is received by the Identity parameter.

Outputs

None

Notes

• This cmdlet does not work with Active Directory Lightweight Directory Services.
