[Samba] first logon always fails

I use winbind on Linux for authentication (using ADS acounts) on many
servers and it works very well on all of them. I use the same configuration
and the same Domain Controllers etc..

I have 4 new servers which are all in a special network segment (behind a
load balancer). On all of them I have the problem, that when I try to logon
with my Active Diretory Account, it says "permission denied". If I try it
again it works. Always! After that I can logon and logoff as many times as i
want, it always works without problems. If i (and also non if the other
users) do not logon for some hours, it starts again: first logon does not
work, all following logons work without problems.

ADS administrators told me they have no entry in theyr log for the faild

Any ideas?

I am actually not sure if this is the right place for these kind of
questions. So feel free to redirect me elsewhere if my question has landed
in the wrong place.
