Hello,

I have two servers, one production and one test/development server both with Windows Server 2008 R2 Service Pack 1 and latest DotNetNuke version 7.1.2. Both should be identically configured but I can not guarantee this, because I am not the only one with admin rights on both servers.

After update from 7.1.0 over 7.1.1 to 7.1.2 Active Directory authentication does no longer work on the production server but still works on test server. Both servers had AD provider 5.0.4 installed. Configuring the AD Provider did work on prod server and I got the list of domains in the AD forest when saving the configuration. When opening the configuration again, not all configured fields were filled, but I could find the field values in the database table. On test server there were no configuration errors. It was not possible to log into prod server using a AD account "Login failure" in log. And  page load exception after that

I updated AD provider to 5.0.5 but I still can not login using an AD account on prod server.

Many THX for any kind of help solving this problem.
