We recently moved off of Novell and are now using Active Directory only, before Novell was taking care of our password policy but now we would like AD to. First we need to remove the Password never expires check box for all user account in a CSV file. I only found commands that will list but not change the setting. Can you please help.

Try a simple csv for starters with a few test users. Remember, when we call on the csv file for the SamAccountName we are looking for a variable that AD can search for that is valid. So if the identities below that heading int he csv file are not valid, then it will fail. If the names contain spaces they would need to be enclosed in quotes.

Hi All,
Our Org default is to not allow password never expires. However, for operational needs, admins can change this setting per account as needed. I would like to know if anyone can direct me to a powershell script to force the bit back to false. I would want to run this on specific AD OUs and not the whole tree. The thought is we can do cleanup if an admin forgets to set this bit back after the need.

Has anyone effectively utilized a parameter to query user accounts with expired or passwords expiring using -PasswordExpired Cmdlet? I need to find expired passwords and/or passwords expiring in our organization not necessarily expiring accounts.

For some reason or the other all of our accounts are set password never expires which makes this more difficult. At least from what I can tell in the attributes listing in ADUC. I will check with higher admins on password policy.

In this post, we will discuss how to set or remove the Password Never Expires check box in Active Directory User object properties under the Account tab. Using this script mentioned in this post, you can do it for single or multiple users accounts.

This script relies on Get-ADUser and Set-ADUser cmdlets in ActiveDirectory module. So make sure it is installed before you run this script. Script has two inputs. First one is list of user accounts for which you want to set or remove the password never expires option. The user accounts list can be from a text file with one user account per line or can be passed directly to the parameter as a comma separated values. Second input is what is operation you want to perform, i.e set or remove operation.

You can look at the example section below to understand how to use this script. The output of the script will clearly indicate the status for each account whether it has enabled it or there are some errors etc.

In this article, I showed you two options to get a list of users with password never expires. There are times when system administrators set account passwords to never expire and this can weaken your AD security.

As I mentioned in this article, you should have a domain password policy configured that requires users to change their password on a regular basis (for example, 60 days). To keep track of accounts that have the password never expires attribute enabled you should run regular reports on all user accounts. The AD Pro toolkit makes it very easy to generate reports on all user accounts.

The PwdLastSet attribute is an Active Directory attribute that stores information about the last time a password was changed for an object. This value type is a LargeInteger representing dates as the number of 100-nanosecond intervals since January 1, 1601, 12:00 AM. The time is always stored in Greenwich Mean Time (GMT). The PasswordLastSet property converts this LargeInteger into a date-time value in the current time zone.

If a user has a recent value for LastLogon but is missing PasswordLastSet, it indicates that the user must change their password at their next logon, with PwdLastSet being set to 0.

Getscreen.me is a cloud-based software providing a remote access via a browser. Connection is performed via a link without installing additional programs. The service is suitable for administration, technical support, as well as for remote connection to an office computer from home. Windows, macOS, Linux and Android versions are available.

But where did these values come from? The UserAccountControl is 4 Bytes which contains 32 bits (Binary). These are bits flags (1 or 0). The Password Never Expires bit is the 15th bit. So some conversion may be required to convert the value from decimal to binary.

To change the value of the PwdLastSet attribute, you can use various tools such as the Active Directory Users and Computers console, the Set-ADUser cmdlet in PowerShell, or an LDAP editor such as LDP.

To call a class in PowerShell, use the class name between brackets [ ], so its [DateTime] and to call the method in the class, use a double-colon :: and type the FromFileFormat method.

To read the PwdLastSet attribute of an Active Directory User, we can use the Get-ADUser cmdlet in PowerShell. For example, to retrieve the PwdLastSet value for a user with the SamAccountName Test, we can run the following line.

You might need to run a query in your Active Directory to get a list of users with passwords older than a number of days. This can be a good start to sending users a notification about their password expiry so they change it before it expires.

The msDS-UserPasswordExpiryTimeComputed value calculation is the same as PwdLastSet, a none readable date format. We can use the same method for the PwdLastSet to convert it to a readable format.

One other thing is that msDS-UserPasswordExpiryTimeComputed takes in to account Fine Grained Password Policies. So if a AD user is assigned a Fine Grained Password Policies and the policy dont require a password age, then the msDS-UserPasswordExpiryTimeComputed will be never, even though the Password Never expires is not checked

Thanks for the comment.
I wrote a section about the UserAccountControl and how to do the calculation. It was fun.
And also pointed out the msDS-UserPasswordExpiryTimeComputed and the fine-grained password policies.

The Set-AdmUser cmdlet modifies the properties of a user. You can modify commonly used property values by using the cmdlet parameters. Property values that are not associated with cmdlet parameters can be modified by using the Add , Remove , Replace , and Clear parameters.

The Identity parameter specifies the user to modify. You can identify a user by their distinguished name (DN), GUID, security identifier (SID), Username (userPrincipalName), or Security Accounts Manager (SAM) account name. You can also set the Identity parameter to an object variable such as $, or you can pass an object through the pipeline to the Identity parameter. For example, you can use the Get-AdmUser cmdlet to retrieve a user object and then pass the object through the pipeline to the Set-AdmUser cmdlet.

The Instance parameter provides a way to update a user object by applying the changes made to a copy of the object. When you set the parameter to a copy of a user object that was modified, the Set-AdmUser cmdlet makes the same changes to the original user object. To get a copy of the object to modify, use the Get-AdmUser cmdlet. The Identity parameter is not allowed when you use the Instance parameter.

This command gets all the users located in the OU=HumanResources,OU=UserAccounts,DC=FABRIKAM,DC=COM organizational unit and sets their DisplayName property concatentation of the Surname and GivenName properties.

This command modifies the user GlenJohn by removing glen.john from the otherMailbox property, adding fabrikam.com to the url property, replacing the title property with manager and clearing the description property.

Specifies the expiration date for an account. When you set this parameter to 0, the account never expires. This parameter sets the AccountExpirationDate property of an account object. The schema name of the property is accountExpires.

Use the DateTime syntax when you specify this parameter. Time is assumed to be local time unless otherwise specified. When a time value is not specified, the time is assumed to be 12:00:00 AM local time. When a date is not specified, the date is assumed to be the current date.

Specifies whether the security context of the user is delegated to a service. When this parameter is set to $true, the security context of the account is not delegated to a service even when the service account is set as trusted for Kerberos delegation. This parameter sets the AccountNotDelegated property for an account. This parameter also sets the ADS_UF_NOT_DELEGATED flag of the User Account Control (UAC) attribute.

Specifies the DNS name of an Adaxes service that will be used to execute this cmdlet. If this parameter is not specified, and the cmdlet is running from an Adaxes Active Directory provider drive, the value for this parameter can be determined from the current path. For example, if the current path is Adaxes:/example.com, the Adaxes service on example.com will be used. If the parameter is not specified and the service DNS name can't be determined from the current path, the cmdlet will access Active Directory directly. To perform an operation in a Microsoft Entra managed domain, you must specify this parameter.

Specifies values to add to an object property. Use this parameter to add one or more values to a property that cannot be modified using a cmdlet parameter. To modify an object property, use its schema name. You can specify multiple values to a property by specifying a comma-separated list of values, and more than one property by separating them using a semicolon. The format for the parameter is:
