Sintaxis

Parameter Set: Default
Set-ADDefaultDomainPasswordPolicy [-Identity] <ADDefaultDomainPasswordPolicy> [-AuthType <ADAuthType> {Negotiate | Basic} ] [-ComplexityEnabled <Boolean> ] [-Credential <PSCredential> ] [-LockoutDuration <TimeSpan> ] [-LockoutObservationWindow <TimeSpan> ] [-LockoutThreshold <Int32> ] [-MaxPasswordAge <TimeSpan> ] [-MinPasswordAge <TimeSpan> ] [-MinPasswordLength <Int32> ] [-PassThru] [-PasswordHistoryCount <Int32> ] [-ReversibleEncryptionEnabled <Boolean> ] [-Server <String> ] [-Confirm] [-WhatIf] [ <CommonParameters>]

Descripción detallada

The Set-ADDefaultDomainPasswordPolicy cmdlet modifies the properties of the default password policy for a domain. You can modify property values by using the cmdlet parameters.

The Identity parameter specifies the domain whose default password policy you want modify. You can identify a domain by its distinguished name, GUID, Security Identifier (SID), DNS domain name, or NETBIOS name. You can also set the parameter to an ADDomain object variable, or pass an ADDomain object through the pipeline to the Identity parameter. For example, you can use the Get-ADDomain cmdlet to retrieve a domain object and then pass the object through the pipeline to the Set-ADDefaultDomainPasswordPolicy cmdlet.

Parámetros

-AuthType<ADAuthType>

Specifies the authentication method to use. Los valores aceptables para este parámetro son los siguientes:

-- 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.

-ComplexityEnabled<Boolean>

Specifies whether password complexity is enabled for the password policy. If enabled, the password must contain three of the following four character types:

-- Uppercase characters (A, B, C, D, E, ...)
-- Lowercase characters (a, b, c, d, e, ...)
-- Numerals (0, 1, 2, 3, ...)
-- Special characters (#, $, *, %, ...)

This parameter sets the ComplexityEnabled property of a password policy. Los valores aceptables para este parámetro son los siguientes:

-- $False or 0. Disables password complexity.
-- $True or 1. Enables password complexity.

-Credential<PSCredential>

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.

-Identity<ADDefaultDomainPasswordPolicy>

Specifies an Active Directory domain object by providing one of the following property values. The identifier in parentheses is the Lightweight Directory Access Protocol (LDAP) display name for the attribute. All values are for the domainDNS object that represents the domain. Los valores aceptables para este parámetro son los siguientes:

-- A distinguished name
-- A GUID (objectGUID)
-- A security identifier (objectSid)
-- A DNS domain name
-- A NetBIOS domain name

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 domain object instance.
