Ini settings before upgrading were changed to

Handler=ezpSessionHandlerDB

in order to have old session management available. After following the upgrade manual on docs.ez.no it is impossible to login successfully. Doing

var_dump( eZSession::get() );

in index.php delivers

array(2) { ["LastAccessedModifyingURI"]=> string(0) "" ["eZUserLoggedInID"]=> string(2) "14" }

after logging in as admin user, but header_links.tpl does not show the user. When adding

{$current_user|attribute(show)}

to header_links.tpl it shows

is_logged_in=false

login=anonymous

Truncating ezsession table resets information for var_dump.

After setting

DebugByUser=disabled

login shows same information in header_links.tpl and var_dump. Setting

DebugByUser=enabled

Leads to unusable login.

Steps to reproduce

Still needs to be done on clean installs.
