Get-ADAuthenticationPolicySilo

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.

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 a query string that retrieves Active Directory Domain Services objects. This string uses the Windows PowerShell expression language syntax. The Windows PowerShell expression language syntax provides rich type-conversion support for value types received by the Filter parameter.

Specify the Filter parameter in one of the following formats:

• To match a single filter element: {Attribute operator "value"}
• To match multiple filter elements: {(Attribute1 operator1 "value1") joinOperator (Attribute2 operator2 "value2")}

Windows PowerShell wildcards other than *, such as ?, are not supported by the Filter syntax.

Valid filter operators are:

-eq, -le, -ge, -ne, -lt, -gt, -approx, -bor, -band, -recursivematch, -like, -notlike

Valid join operators are:

-and, -or

The not operator is -not.

For a list of supported types for values, see about_ActiveDirectory_ObjectModel. For more information about the Filter parameter, see about_ActiveDirectory_Filter.

Specifies an Active Directory Domain Services authentication policy silo object. Specify the authentication policy silo object in one of the following formats:

• A distinguished name
• A GUID
• A 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.

Specifies a filter using the LDAP search filter syntax defined in RFC2254 to filter Active Directory Domain Services objects.

Specifies the properties of the output object to get from the server. Use this parameter to get properties that are not included in the default set.

Specify the properties to get as a comma separated list of names. For properties that are not default or extended properties, you must specify the LDAP display name of the property. To display all of the properties that are set on the object, specify an asterisk (*) wildcard.

Specifies the number of objects to include in one page for an Active Directory Domain Services query. The default value is 256 objects per page.

Specifies the maximum number of objects to return for an Active Directory Domain Services query. If you want to get all of the objects, set this parameter to $null. You can use Ctrl+C to stop the query and the return of objects.

The default value is $null.

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
