Hi again,
some time ago I was able to solve my issue. It was some kind of misconfiguration.
I really underrated the amount of data Piwik has to process with my monitored sites and so I haven´t activated the cron to archive the stats...
If you are interested in further details, view my blog post (German) about it: http://www.nobbis.net/de/nobbis-blog/themen-aus-dem-web/155-piwik-und-mein-problem-mit-dem-login.html
Cheers and thanks for trying to help me...
