My guess was that you have not created the "/tmp/http_sessions" directory. Note that the "successfully logged in" message is shown even if the login fails. You must see the user home page if the login is really successful (i.e., create event, logout, … must be visible). The login failure message is also generated when the quality of service is not good and SOME users fail to login. However, in your case ALL login attempts fail which does not look like a QoS problem. 25 concurrent users is too small to saturate the system. You should be able to get good QoS (no failure) for ~750 users per core on a typical system.
