Dan, I'll try to remember to test with a locked-out account tonight to see what happens. I know your users account isn't locked out but I want to see what error message is returned. Other than that I'm not sure what I can do to recreate the issue and debug it.

I'll also do some hunting at home. I used to have a small web app that just did authentication against the domain but I don't have it posted anywhere anymore. I'll see if I can find it and possibly we can use that for testing.

I wasn't having any luck with the current release version, so I installed the beta to test it out...

Honestly, I don't think it is a case of actually being locked out, but interpreting it as such. I was playing around in the DNN database this morning, removing all references to his account, so will have him test again.

I don't know if you have figured it out yet but I had a similar problem yesterday.

In the end I found references in the aspnet_Users and aspnet_Membership that hadn't been deleted.

I removed them and found the user could log in again.

Jacqui.
