Description

The Get-ADAuthenticationPolicy cmdlet gets an authentication policy or performs a search to get authentication policies.

The Identity parameter specifies the Active Directory Domain Services authentication policy to get. You can identify an authentication policy by its distinguished name, GUID or name. You can also use the Identity parameter to specify a variable that contains an authentication policy object, or you can use the pipeline operator to pass an authentication policy object to the Identity parameter.

You can search for and use multiple authentication policies by specifying the Filter parameter or the LDAPFilter parameter. The Filter parameter uses the Windows PowerShell® expression language to write query strings for Active Directory Domain Services. Windows PowerShell expression language syntax provides rich type conversion support for value types received by the Filter parameter. For more information about the Filter parameter syntax, type Get-Help about_ActiveDirectory_Filter. If you have existing Lightweight Directory Access Protocol (LDAP) query strings, you can use the LDAPFilter parameter.

Examples

Example 1: Get an authentication policy

PS C:\> Get-ADAuthenticationPolicy -Identity AuthenticationPolicy01

This command gets an authentication policy object by specifying the object name.

Example 2: Get an authentication policy by using an LDAP filter

PS C:\> Get-ADAuthenticationPolicy -LDAPFilter "(name=AuthenticationPolicy*)" -Server Server01.Contoso.com

This command gets all authentication policies that match the LDAP filter specified by the LDAPFilter parameter.

Example 3: Get an authentication policy by using a filter

PS C:\> Get-ADAuthenticationPolicy -Filter "Name -like 'AuthenticationPolicy*'" -Server Server02.Contoso.com

This command gets all authentication policies that match the filter specified by the Filter parameter.

Example 4: Get all authentication policy objects that match a filter

PS C:\> Get-ADAuthenticationPolicy -Filter * | Format-Table Name, Enforce -AutoSize
Name                   Enforce
----                   -------
AuthenticationPolicy1   False
AuthenticationPolicy2   False

This command gets all the authentication policies available. The output is then passed to the Format-Table cmdlet to display the name of the policy and the value for Enforce on each policy.

Example 5: Get all properties for an authentication policy

PS C:\> Get-ADAuthenticationPolicy -Identity "AuthenticationPolicy01" -Properties "*"

This command gets all properties of the authentication policy specified by the Identity parameter.

Parameters

-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

-Credential

Specifies a user account that has permission to perform the task. The default is the current user. Type a user name, such as User01 or Domain01\User01, or enter a PSCredential object, such as one generated by the Get-Credential cmdlet.

By default, the cmdlet uses the credentials of the currently logged on user unless the cmdlet is run from an Active Directory Domain Services Windows PowerShell provider drive. If you run the cmdlet in a provider drive, the account associated with the drive is the default.

If you specify credentials that do not have permission to perform the task, the cmdlet returns an error.

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

-Filter

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: {Attributeoperator "value"}
  • To match multiple filter elements: {(Attribute1operator1 "value1") joinOperator (Attribute2operator2 "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.

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

-Identity

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

  • A distinguished name
  • GUID
  • 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.

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

-LDAPFilter

Specifies an LDAP query string used to filter Active Directory Domain Services objects. Use this parameter to run your existing LDAP queries.

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

-Properties

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.

To get properties for an object and display them, you can use this cmdlet and pass the output to the Get-Member cmdlet by using the pipeline operator.

Type:String[]
Aliases:Property
Position:Named
Default value:None
Required:False
Accept pipeline input:False
Accept wildcard characters:False

-ResultPageSize

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.

Type:Int32
Position:Named
Default value:None
Required:False
Accept pipeline input:False
Accept wildcard characters:False

-ResultSetSize

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.

Type:Int32
Position:Named
Default value:None
Required:False
Accept pipeline input:False
Accept wildcard characters:False

-Server

Specifies the Active Directory Domain Services instance to which to connect, 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

Inputs

None or Microsoft.ActiveDirectory.Management.ADAuthenticationPolicy

This cmdlet accepts an authentication policy object.

Outputs

ADAuthenticationPolicy

This cmdlet returns one or more authentication policy objects. This cmdlet returns a default set of ADAuthenticationPolicy property values. To retrieve additional ADAuthenticationPolicy properties, use the Properties parameter.
