Detailed Description

The Get-ADDomainControllerPasswordReplicationPolicy gets the users, computers, service accounts and groups that are members of the applied list or denied list for a read-only domain controller's (RODC) password replication policy. To get the members of the applied list, specify the AppliedList parameter. To get the members of the denied list, specify the DeniedList parameter.

The Identity parameter specifies the RODC that uses the allowed and denied lists to apply the password replication policy. You can identify a domain controller by its GUID, IPV4Address, 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 (DN) of the NTDS settings object or the server object, the GUID of the NTDS settings object or the server object under the configuration partition, or the DN 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 retrieve a domain controller object and then pass the object through the pipeline to the Get-ADDomainControllerPasswordReplicationPolicy cmdlet.

If you specify a writeable domain controller for this cmdlet, the cmdlet returns a non-terminating error.

Parameters

Allowed

Specifies that the cmdlet should return the users, computers, and groups from the domain controller allowed list.

The following example shows how to specify this parameter.
-AllowedList

AuthType

Specifies the authentication method to use. Possible values for this parameter include:
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.

The following example shows how to set this parameter to Basic.
-AuthType Basic

The following lists the acceptable values for this parameter:

  • Negotiate

  • Basic

Default Value: Microsoft.ActiveDirectory.Management.AuthType.Negotiate

Data Type: ADAuthType

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 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 The following example shows how to create credentials.
$AdminCredentials = Get-Credential "Domain01\User01"

The following shows how to set the Credential parameter to these credentials.
-Credential $AdminCredentials

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

Default Value:

Data Type: PSCredential

Identity

Specifies an Active Directory account object by providing one of the following property values. The identifier in parentheses is the LDAP display name for the attribute.

Distinguished Name
Example: CN=SaraDavis ,CN=Users,DC=corp,DC=contoso,DC=com
GUID (objectGUID)
Example: 599c3d2e-f72d-4d20-8a88-030d99495f20
Security Identifier (objectSid)
Example: S-1-5-21-3165297888-301567370-576410423-1103
SAM Account Name (sAMAccountName)
Example: saradavis

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 account object instance.

Derived types such as the following are also accepted:
Microsoft.ActiveDirectory.Management.ADUser
Microsoft.ActiveDirectory.Management.ADComputer
Microsoft.ActiveDirectory.Management.ADServiceAccount

This example shows how to set the parameter to a distinguished name.
-Identity "CN=saradavis,CN=Users,DC=corp,DC=contoso,DC=com"

This example shows how to set this parameter to an account object instance named "accountInstance".
-Identity $accountInstance

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.
Domain name values:
Fully qualified domain name
Examples: corp.contoso.com
NetBIOS name
Example: CORP

Directory server values:
Fully qualified directory server name
Example: corp-DC12.corp.contoso.com
NetBIOS name
Example: corp-DC12
Fully qualified directory server name and port
Example: corp-DC12.corp.contoso.com:3268

The default value for the Server parameter is determined by one of the following methods in the order that they are listed:
-By using Server value from objects passed through the pipeline.
-By using the server information associated with the Active Directory PowerShell provider drive, when running under that drive.
-By using the domain of the computer running Powershell.

The following example shows how to specify a full qualified domain name as the parameter value.
-Server "corp.contoso.com"

Microsoft.ActiveDirectory.Management.ADPrincipal


Returns one or more objects that represent the users, computers, service accounts and groups that are members of the applied list or denied list of the domain controller password replication policy. The list returned depends on the parameters specified.

Notes


  • This cmdlet does not work with AD LDS.
    This cmdlet does not work when targeting a snapshot using the Server parameter.
