Hi all,
actual we have a Problem with the Login for AD Users. We have two domains (A & B). The Portal runs in Portal A, Users from A don't have any problems. I actived the automatic login for the users, this is working for boths domains. But if a User of Domain B logoff and want to login again, we get the message "Login Failed. Please remember that passwords are case sensitive".  If the user call "*DesktopModules/AuthenticationServices/ActiveDirectory/WindowsSignin.aspx" he will be logged in again.

In the Event Viewer i receive the following Message:

Is that a known Bug or maybe is there a fix for that? I found many threads with nearly the same problem, but without any solution for me.
Regards,

we are using domain\user for both domains.

Are there any tests which i could make to get more details?
A Suggestion from an other thread was that I maybe don't have the neccessary rights to check the other domain, but in this case the automatic login shouldn't work or?
