This is a bit of problem with 7.1, I reported a bug here:
https://dnntracker.atlassian.net/brow...

In the bug report (I should update it), I've stated that we can login via the windows signin page, but this is slightly wrong. For some reason it works on our dev/staging instance, but not our prod one. 

I'm currently trying to create a debug build of the provider from the source so I can remote debug it on our dev instance. Having trouble getting it to build with the 7.1 assemblies & the DotNetNuke.Membership.DataProvider dll seems to have disappeared from a previous version so I can't reference it. So will try previous versions of the 2 referenced assemblies, so I can get something to test against.

I've now got a debug build & can remote debug. It looks like the exception is being thrown by DNNUserController.ChangePassword(objUser, strStoredPassword, strRandomPassword) on line 564 in AuthenticationProvider.vb. I've checked and objUser.UserID definitely has a value, so it appears the problem is not in the provider itself, but somewhere in DotNetNuke.Entities.Users.UserController.ChangePassword()

For reference to get the source to build with the 7.1.x assembly you need to (in addition to the fiddling with the project file):

  1. Set the target framework to .NET 4
  2. Add a reference to System.Web.ApplicationServices
  3. Change lines 371 & 559 in AuthenticationProvider.vb to use the fully qualified namespace for the calls to Membership.GetUser(objUser.Username) so it becomes System.Web.Security.Membership.GetUser(objUser.Username)

 BTW - It doesn't seem to matter that there is not reference to DotNetNuke.Membership.DataProvider mentioned above

After getting a working build and modifying it so I could login. I found a setting in Host Settings -> Advanced Settings -> Membership management, that allows you to turn off password history. After turning this off I was able to go back to using the non-modified version of the ad provider assembly.

If you can't login to your site because of password history & have access to the database you can turn it off manually by finding the EnablePasswordHistory row in the dnn_HostSettings table and setting it's value to N
