Which solution Dan? The one I posted a link to? With the separation of the providers the script just goes on the login.ascx for the AD provider so your normal users never see it.

That said, I've added an enhancement for the next release that will allow you set a default domain in the settings and the user won't have to enter the domain name. If you've got a test site you can get it from my site (http://dnn.gmss.org).

Oh.... My mistake, I read through the code, but didn't pay attention to the location of the file.  That just might work here then!
