Have upgraded my Jira installation from 8.0.2 to 8.2.2. Now I can't login anymore. secure/Dashboard.jspa says invalid user or wrong password. But it is not. If I call an issue directly (e.g. /browse/#issueno) I get a login screen and can access the issue. Found no log entries for invalid credentials. In atlassian-jira-security.log are some wierd entries that the user passes the authentication and immediatly the session was destroyed.
