The so called "session_data_manager" tells Zope where the
"session_data" is located.

Apparently, your "session_data_manager" does not look at
the place of your mount point or your mount point does not work/is not
active.

First verify the "session_data_manager" configuration (this easy -- look
in the ZMI).
If this is correct, verify the mount point.
That is not so easy. The best way is to start an interactive
Python interpreter ("bin/zopectl debug" on *nix).
Then use

     folder = app.unrestrictedTraverse('path_to_folder_containing_the_mount')
     folder._p_activate() # load the folder
     folder.__dict__['Id_of_your_mount_point']

You should see an "ZODBMountPoint" (or something along this lines).

If you really see a mount point, verify its configuration
(that's easy again -- thus, you can do that before the more
difficult step): is the mount point really in the storage you want?
