Nakisa AD form Authentication

Hi Colleagues,

We have configured Nakisa OrgChart AD form authentication, We have checked it in 4.0 and was right, but now we are upgraded to 4.0 SP1 and when we try to login the system return allways the error:invalid login. We are using the same configuration and the same AD admin user/password.

Someone know if could be any problema with AD form in SP1?

Regards,

Albano
