Set-ADForest

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

Prompts you for confirmation before running the cmdlet.

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.

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

Fully qualified domain name

Example: corp.contoso.com

GUID (objectGUID)

Example: 599c3d2e-f72d-4d20-8a88-030d99495f20

DNS host name

Example: dnsServer.corp.contoso.com

NetBIOS name

Example: corp

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 a forest object instance.

This example shows how to set the parameter to a fully qualified domain name.

-Identity "corp.contoso.com"

This example shows how to set this parameter to a forest object instance named "forestInstance".

-Identity $forestInstance

Returns the new or modified object. By default (i.e. if -PassThru is not specified), this cmdlet does not generate any output.

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"

Modifies the list of service principal name (SPN) suffixes of the forest. This parameter sets the multi-valued msDS-SPNSuffixes property of the cross-reference container. This parameter uses the following syntax to add remove, replace, or clear SPN suffix values.

Syntax:

To add values:

-SPNSuffixes @{Add=value1,value2,...}

To remove values:

-SPNSuffixes @{Remove=value3,value4,...}

To replace values:

-SPNSuffixes @{Replace=value1,value2,...}

To clear all values:

-SPNSuffixes $null

You can specify more than one change by using a list separated by semicolons. For example, use the following syntax to add and remove SPN suffix values

@{Add=value1,value2,...};@{Remove=value3,value4,...}

The operators will be applied in the following sequence:

..Remove

..Add

..Replace

The following example shows how to add and remove SPNSuffixes for a forest.

-@{Add="ContosoEurope", "ContosoAsia"};@{Remove="Contoso"}

Modifies the list of user principal name (UPN) suffixes of the forest. This parameter sets the multi-valued msDS-UPNSuffixes property of the cross-reference container. This parameter uses the following syntax to add remove, replace, or clear UPN suffix values.

Syntax:

To add values:

-UPNSuffixes @{Add=value1,value2,...}

To remove values:

-UPNSuffixes @{Remove=value3,value4,...}

To replace values:

-UPNSuffixes @{Replace=value1,value2,...}

To clear all values:

-UPNSuffixes $null

You can specify more than one change by using a list separated by semicolons. For example, use the following syntax to add and remove UPN suffix values

@{Add=value1,value2,...};@{Remove=value3,value4,...}

The operators will be applied in the following sequence:

..Remove

..Add

..Replace

The following example shows how to add and remove UPN suffixes for a forest.

-UPNSuffixes @{Add="Fabrikam.Com", "Corp.Fabrikam.Com"}; @{Remove="NA.Fabrikam.Com","Europe.Fabrikam.Com"}

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