I recently installed qdPM 7.0 and configured it for several users. When I asked my colleagues to test their account, everything was OK until the second person connects. They were actually entering each other's session.
qdPM is installed on a server accessible only from the Internet.
When user A connects, there is no problem, but when user B connects, user A finds himself using user B's session and vice versa.
It looks like it is not using cookies correctly. We've tested this on different machines with the same result.
I need to say that at the same time I'm connected with my admin account behind the same nat'ed IP and I have no problem. I also asked another colleague in a different site to test his account and hw didn't encounter any issue.
Thank you for telling me where I need to modify the PHP or Symphony settings to avoid this.
