Does anybody know how to disable active directory directly on the database.

I mean i want to know which field and table i need to change.

My version of dotnetnuke  is 4.4

Thanx in advance.

In DNN 4.4 the AD code was integrated in the DNN core code and it didn't have a separate way of enabling/disabling it. Sebastan's solution would be the ideal for stopping the auto-login attempt. If you look in the <httpModules> section just comment out any lines that start <add name="Authentication".... />. That will stop any attempts at automatic login.

If that solution doesn't work for you then perhaps a fully explanation of what you're trying to do or the problem you're having would help.
