I am trying to get a basic auto sync and login integration with AD working on a new install for my intranet, but for some reason I can either have the site auto login users or auto sync from AD, but not both at the same time.  Below are the specifics:

Server 2008 R2
DNN: 6.2.1
AD Authentiation: 5.0.4
IIS: 7.5
AppPool: Classic

I have configured the AD Module as per the documentation.

In IIS, if I have enabled only Windows Authentication and NOT Forms Authentication, then for users with existing accounts in DNN, the auto login works just fine.  However, users who do not have accounts end up in an endless loop and are not able to login - no accounts are created automatically.

If I enable both Windows and Forms Authentication, DNN does not automatically log users in.  If existing or new users click Login, they are able to login with no issues.  New user accounts are created when the new user logs in for the first time.

Basically, I'd like the system to automatically log in users and created accounts if they don't exist.

I know there are many posts on this, but I have not been able to diagnose this specific problem through my research.  Any insight would be much appreciated.

Thanks,

Craig

Thanks for the quick reply.

Yes, that's correct, I did it for the whole site because when I try to do if for just the windowssignin.aspx file I receive the following error:

web.config
Line number: 450
Error: This configuration section cannot be used at this path.  This hapens when the section is locked at a parent level.  Locking is either by default (overrideModeDefault="Deny"), or set explicitly by a location tag with overrideMode="Deny" or the legacy allowOverride="false"

I cannot find anything in the web.config that refers to an override.

Thanks,

Craig
