Passwords that never expire
This week's tip is by Roan Daley, a Premier Field Engineer at Microsoft.
Finding Active Directory objects that have Password Never Expires
As an Active Directory PFE, one of the issues I typically address with administrators is to identify objects (computers or users) that have Password Never Expires. From security perspective, this is considered a risk. For most environments, the easiest way to do this is to use the DS query command:
dsquery * domainroot -filter "(&(objectClass=user)(UserAccountControl:1.2.840.1135188.8.131.523:=65536))" -attr sAMAccountName userPrincipalName userAccountControl -d contoso.com
dsquery * domainroot -filter "(&(objectClass=computer)(UserAccountControl:1.2.840.1135184.108.40.2063:=65536))" -attr cn userAccountControl -d contoso.com
For Window 2008 R2 and above this is even easier with the advent of the Active Directory PowerShell Modules:
Search-ADAccount -PasswordNeverExpires | FT Name,ObjectClass -A
Search-ADAccount –PasswordNeverExpires - ComputersOnly | FT Name,ObjectClass –A
Hope these tips help with keeping you AD Clean!
