Question

minRequiredPasswordLength setting is being ignored

Asked by: TornadoV

minRequiredPasswordLength="4" setting is being ignored when I run the fragment of code below against ADAM instance installed on Windows 2003 server.  I get the "membershipcreatestatus.invalidpassword" error.  When 6 digit password is being supplied then there is no error and user is being created just fine, unfortunately the requirement is to allow 4 digit passwords.

Mention must be made that this code runs fine against ADAM instance on Windows XP Pro machine.  I am able to replicate the user from Win XP instance to Windows Server 2003 instance after it is created with a 4 digit password on Win XP ADAM instance.

Code fragment:
MembershipCreateStatus status;
Membership.CreateUser(stringUsername, stringPwd, stringUsername, stringQuestion, stringAnswer, true, out status);
if (status == MembershipCreateStatus.Success)
{
          blah, blah, blah...
}

Config setting:
minRequiredPasswordLength="4"
minRequiredNonalphanumericCharacters="0"

Any ideas?

Just a hunch here..

Have you tried setting the minRequiredPasswordLength to 3 instead?

If my gut feeling is correct, the way it is now would suggest that in that case 4 would work, whereas 3 would not...or in any other case...with this setting you have now...do 5-digit passwords get accepted?

Regards,
Max.

Thanks Max, I have tried setting it to 3 and 5, same result.  Works fine for Win XP instance, invalidPassword error for Windows Server 2003.  

 

by: TornadoVPosted on 2007-08-23 at 08:28:23ID: 19755221

It looks like server's local policy setting "Minimum password length: 6 characters" is overriding my minRequiredPasswordLength = "4".  Not sure why.  I tried to change that setting on the server but it is disabled since it's being controlled by active directory policy.

 

by: DreamMasterPosted on 2007-08-23 at 23:46:09ID: 19760164

Normally Active Directory settings do take precedence over the settings you make in a program. Strange however that you cannot change those settings in the Active Directory policy.

Is this problem consistent with different windows versions? There have been some minor differences known between different environments...

Also, have you tried to set the following in your web.config:

<location allowOverride="true">

Regards,
Max.

 

by: TornadoVPosted on 2007-08-27 at 06:38:02ID: 19775345

Thanks Max, I've tried and it didn't help.  It looks like a bug to me and I'm going to submit it to Microsoft.

Here is what I got from Microsoft:

The password settings on ActiveDirectoryMembershipProvider can only enforce more restrictive/additional password rules than what is allowed by the local security policy of the machine on which ADAM is running. Check the Local Security Policy MMC to see the machine's effective password policy. From the repro steps it sounds like the machine's local security policy probably enforces a minimum of 6 characters for password lengths.

Basically it is done by design but I couldn't find that info anywhere.
