Parameters
-AllowedList (required)
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)
-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.
-Confirm
Prompts you for confirmation before running the cmdlet.
-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. Specifies the credentials for the security context under which the task is performed. If this security context doesn't have directory level permissions to perform the task, then an error is returned by the directory. If running under the context of an Active Directory module for Windows PowerShell provider drive, the credentials information associated with the drive is used as the default value; otherwise, the currently logged on user security context is used.
-DeniedList (required)
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 SAM account name (sAMAccountName)
-Identity (required)
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.
-PassThru
Returns an object representing the item with which you are working. By default, this cmdlet does not generate any output.
-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
-WhatIf
Shows what would happen if the cmdlet runs. The cmdlet is not run.
