Sorry for the inconvenience. I’m responsible for most of the Login changes going into 1.1.
Are you using a reverse proxy? In 1.1, the proxy headers are configureable. (The update script is targeted for 1.1, so it wouldn’t have been run when updating to 1.1b4.) See config/global.ini.php’s proxy_client_headers[] and proxy_server_headers.
Otherwise:
is the login failing for all users?
What php version?
Are you getting any errors or warnings on the screen or in the web server logs?
jOoL: ok, from your weblog, I can see the POST for the login form, and the 302 redirect. If you got sent back to the login form without a warning/error, then it means Piwik authenticated your login successfully, and sent back a cookie (piwik_auth). Check your browser settings/addons/extensions to make sure cookies are enabled and aren’t being blocked in any way.
