Re: [ActiveDir] Strange password issue

My understanding was that the Password Policies are applied similarly to any other Group Policy. I do recall doing some testing some time ago where by using various security filtering on Group Policies I was able to set up two DC's with two different effective policies and so two different values for Password length.
 
The thing to remember is that domain password changes etc are processed by a domain controller. You therefore need to check whether the Password policy is being applied to all of the domain controllers. As Larry said, if there is blocking on the OU for Domain Controllers and the Default Domain Policy does not have "No Override" then the DC will not get the policy. Similarly, it is possible that security filtering has been applied to the Default Domain Policy that stops it from getting applied etc. However these things would be "permanent" so you would still have a DC with the Policy not applied.
 
However, my guess is that something was wrong a month ago on a Domain Controller which processed the Password reset. It is possible that it is still a problem (i.e. if blocking was the culprit), but it is more likely to have cleared up. Is it possible that there was a DC added briefly at the time that was not processing Policies for some reason?
 
Is it feasible to check all of the event logs on all DC's at the time the password was created? It may show Group Policy Processing errors at the time.

Have you actually seen this behaviour?  As it was my understanding that this particular policy is processed by SCE outside of normal policy application (by the PDCe - I can't remember how often, 60 minutes comes to mind but I don't know why).  I've tried to document this here:

If the Domain Controllers OU is set to block GPO inheritance, and the domain GPO that sets the password policy isn't set for No Override, then the domain policies might not get set properly.

err, actually the password policy is stored in the machine portion of the GPO and thus applies to all machines and therefore all local user objects too.

Impossible/irrelevant. If it's a domain account, the policy applies regardless, because the account is stored in AD. If it's a local account, then the policy doesn't apply regardless; domain account policies don't apply to local accounts. Is this a local account or a domain account?

If you mean before the policy was set up, then, no.
This policy has been in effect for a couple of years and the account was created a month ago..
 
Maybe the PC is not getting the Default Domain Policy?

Tom,

 

This is just a stab in the dark but is it possible that this user's password was set prior to the Default Domain Policy being in effect?

I'm having this weird  issue where I have a user account who is able to log in with a blank password.

The Default Domain Policy is set to a min password length of 6 characters.

The userAccountControl on the user is set to 512.

 

The Domain is at win2k3 DFL and FFL.

 

Is there any other way besides a migration tool like Quest that could circumvent this policy and allow blank passwords?

 

Thanks
