AD Account locked on first wrong password attempt


I have an issue with AD integration of openSuSE 11.2:

I configured AD integration during setup of the system and authentication / login with AD Accounts via different services (sshd, vsftpd, etc) works as expected.

But when i enter the wrong password the AD account will be locked out on the first attempt.

How can i control the behavior of the login procedures to not retry authenticating with a wrong password?

I have already replied with some technical information on this Guys post who is having a similar or maybe the same problem:
