I think I might see a cause to the problem. You say the application pool is running in integrated mode. The 5.0.2 version of the provider doesn't support integrated mode. The 5.0.3 version does support integrated if the two commands that are posted in the readme are run. I'd have to check my dev system @ home as far as using the 4.0 framework. The software was coded under the 3.5 framework and I've seen funky things happen under the 4.0 framework with other software.

I am also getting this error on the login page. My app pool is running in classic. The AD provider is working great except for this login page error. I'm using DNN 6.0, and .NET 4.

Im thinking about just adding a redirect on the login page to the http://myweb.scentsy.local/DesktopModules/AuthenticationServices/ActiveDirectory/WindowsSignin.aspx page. That seems like a hack though, I'd rather just have this provider work.

Hi, just thought I'm mention that we're getting the same error with DNN6 (DN6.0.1). We're using classic (and .NET3.5). I've never had this error in DNN5.x series, so something must have changed in 6 that is causing this issue with oldPassword. Am still investigating it myself, but it definitely is happening to more than just the one person.
thks

i was able to solve this problem by making the following change within the code (we actually converted this AD provider to an LDAP provider a while back, so our code does not match and many places but I'm assuming this line exists in some fashion in the AD code as well (it is actually in multiple places in our LDAP version).

Changed
DNNUserController.ChangePassword(objUser, objUser.Membership.Password, passwordToValidate)

To
DNNUserController.ChangePassword(objUser, DNNUserController.GetPassword(objUser, ""), passwordToValidate)

it looks like in DNN6, objUser.Membership.Password is now returning a null (maybe some security thing??), which causes the 2nd parameter to be null, which causes the ChangePassword method to have an uncaught exception. The GetPassword method I swapped in still returns the current password, so implementing this change, the function now does not bomb.

Hope this helps.

Anyone have a workaround that doesn't require a change to code?  We're having the same/similar issue - see synopsis below.
  - Jason

With the AD provider, some users are able to use the Windows option in the DNN Account Login module to log in one time only.  A DNN user account is successfully created during the initial login but subsequent logins with the Windows option of the Account Login module fail.

The same users are able to use the WindowsSignin.aspx login page to authenticate as needed, so this appears to be a provider or code issue & not a corrupt data issue.  Also, most of our users are able to use the Account Login module without problems - This only affects a few users.  There appears to be a pattern where this affects recently created Windows accounts, but we haven't been able to confirm if that's related.
