Unlock-ADAccount
Unlocks an Active Directory account.
Syntax
Unlock-ADAccount
[-WhatIf]
[-Confirm]
[-AuthType <ADAuthType>]
[-Credential <PSCredential>]
[-Identity] <ADAccount>
[-Partition <String>]
[-PassThru]
[-Server <String>]
[<CommonParameters>]Description
The Unlock-ADAccount cmdlet restores Active Directory Domain Services (AD DS) access for an account that is locked. AD DS access is suspended or locked for an account when the number of incorrect password entries exceeds the maximum number allowed by the account password policy.
The Identity parameter specifies the Active Directory account to unlock. You can identify an account by its distinguished name, GUID, security identifier (SID) or Security Accounts Manager (SAM) account name. You can also set the Identity parameter to an account object variable such as $<localADAccountObject>, or you can pass an object through the pipeline to the Identity parameter. For example, you can use the Search-ADAccount cmdlet to get an account object and then pass the object through the pipeline to the Unlock-ADAccount cmdlet to unlock the account. Similarly, you can use Get-ADUser and Get-ADComputer to get objects to pass through the pipeline.
For Active Directory Lightweight Directory Services (AD LDS) environments, the Partition parameter must be specified except when:
- Using a distinguished name to identify objects: the partition is auto-generated from the distinguished name.
- Running cmdlets from an Active Directory provider drive: the current path is used to set the partition.
- A default naming context or partition is specified.
To specify a default naming context for an AD LDS environment, set the msDS-defaultNamingContext property of the Active Directory directory service agent object (nTDSDSA) for the AD LDS instance.
Examples
Example 1: Unlock an Active Directory account
PS C:\>Unlock-ADAccount -Identity PattiFuThis command unlocks the account with the SAM account name PattiFu.
Example 2: Unlock an Active Directory account using a distinguished name
PS C:\>Unlock-ADAccount -Identity "CN=Patti Fuller,OU=Finance,OU=UserAccounts,DC=FABRIKAM,DC=COM"This command unlocks the account with the distinguished name CN=Patti Fuller,OU=Finance,OU=UserAccounts,DC=FABRIKAM,DC=COM.
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: | Microsoft.ActiveDirectory.Management.AuthType.Negotiate |
| Required: | False |
| Accept pipeline input: | False |
| Accept wildcard characters: | False |
-Confirm
Prompts you for confirmation before running the cmdlet.
| Type: | SwitchParameter |
| Aliases: | cf |
| Position: | Named |
| Default value: | False |
| Required: | False |
| Accept pipeline input: | False |
| Accept wildcard characters: | False |
-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-Credentialhttp://go.microsoft.com/fwlink/?LinkID=293936 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.
| Type: | PSCredential |
| Position: | Named |
| Default value: | None |
| Required: | False |
| Accept pipeline input: | False |
| Accept wildcard characters: | False |
-Identity
Specifies an Active Directory account 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. The acceptable values for this parameter are:
- A distinguished name
- A GUID (objectGUID)
- A security identifier (objectSid)
- A SAM account name (sAMAccountName)
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 account object instance.
Derived types such as the following are also accepted:
- Microsoft.ActiveDirectory.Management.ADServiceAccount
- Microsoft.ActiveDirectory.Management.ADComputer
- Microsoft.ActiveDirectory.Management.ADUser
| Type: | ADAccount |
| Position: | 0 |
| Default value: | None |
| Required: | True |
| Accept pipeline input: | True |
| Accept wildcard characters: | False |
-Partition
Specifies the distinguished name of an Active Directory partition. The distinguished name must be one of the naming contexts on the current directory server. The cmdlet searches this partition to find the object defined by the Identity parameter.
In many cases, a default value is used for the Partition parameter if no value is specified. The rules for determining the default value are given below. Note that rules listed first are evaluated first and once a default value can be determined, no further rules are evaluated.
In AD DS environments, a default value for Partition is set in the following cases:
- If the Identity parameter is set to a distinguished name, the default value of Partition is automatically generated from this distinguished name.
- If running cmdlets from an Active Directory provider drive, the default value of Partition is automatically generated from the current path in the drive.
- If none of the previous cases apply, the default value of Partition is set to the default partition or naming context of the target domain.
In AD LDS environments, a default value for Partition is set in the following cases:
- If the Identity parameter is set to a distinguished name, the default value of Partition is automatically generated from this distinguished name.
- If running cmdlets from an Active Directory provider drive, the default value of Partition is automatically generated from the current path in the drive.
- If the target AD LDS instance has a default naming context, the default value of Partition is set to the default naming context. To specify a default naming context for an AD LDS environment, set the msDS-defaultNamingContext property of the Active Directory directory service agent object (nTDSDSA) for the AD LDS instance.
- If none of the previous cases apply, the Partition parameter will not take any default value.
| Type: | String |
| Position: | Named |
| Default value: | None |
| Required: | False |
| Accept pipeline input: | False |
| Accept wildcard characters: | False |
-PassThru
Returns an object representing the item with which you are working. By default, this cmdlet does not generate any output.
| Type: | SwitchParameter |
| Position: | Named |
| Default value: | None |
| Required: | False |
| Accept pipeline input: | False |
| Accept wildcard characters: | False |
-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 ServicesWindows 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 |
-WhatIf
Shows what would happen if the cmdlet runs. The cmdlet is not run.
| Type: | SwitchParameter |
| Aliases: | wi |
| Position: | Named |
| Default value: | False |
| Required: | False |
| Accept pipeline input: | False |
| Accept wildcard characters: | False |
