cant login in local build service

Hello everybody,

I have the following problem with my local buildservice:
I followed the manual how to install and configure the buildservice for openSuSE 11.0
on the site Build Service/Build Service Installation Tutorial/openSUSE 11.0 - openSUSE
The frontend works but if i start the webclient and try to log me in with the standard user Admin and the passwort, then i get reffered to the same login page again and nothing happens.
I am trying to fix this problem for a long time now and i thought you can help me with it.

My configs are 100% like it says in the manual!

ok now i found the problem…

the problem is called browser caching
