This project is read-only.

Login just one time.


I'm developing an Intranet Application for the company I'm working, and I tried to integrate it with Windows Authentication using this extension, the extension works great the first time the user login with the windows credentials but when they try to login second time something very weird happens. The Error is this:

This Membership Provider has not been configured to support password retrieval.

And this in a different Event

Logon failure: unknown user name or bad password.

I'll be very happy if you can help to solve this.

Thank you so much.

I have the same issue with DNN 7.4.1.

Could you fix this problem by any chance?

I was having the same problem with this module, that the Users from the local Domain Group could only log in once, and then I was getting Logon Failure, because of the way the DNN is set up in saving the passwords.

You have to go to web.config and change the two following attributes: " passwordFormat " from "Hashed" to "Encrypted" and the "enablePasswordRetrieval" form "false to true":

Then you have to log in with your superUser and delete all the Domain Users that you registered ,so you can log in for the first time with them, and have they password be Encrypted and not Hashed.

Hope this helps
