KDM forbid multiple sessions per user

Hi, How is it possible to configure TDM / TDE so that it does allow any user to have more than one session? TDM/Trinity after update to R14, will actually start a second session but the first goes looked. Example: On server logged as supervisor, then on thinstation too, on server goes the session locked. on .xsession-errors [tdecore] Deleting stale lockfile /tmp/tde-supervisor/kdesktop_lock_lockfile TQThreadInstance::start: Setting thread storage to 0xcff130 [tdecore] Deleting stale lockfile /tmp/tde-supervisor/kdesktop_lock_lockfile TQThreadInstance::start: Setting thread storage to 0x92ccc0 [tdecore] Deleting stale lockfile /tmp/tde-supervisor/kdesktop_lock_lockfile TQThreadInstance::start: Setting thread storage to 0x176a220 [tdecore] Deleting stale lockfile /tmp/tde-supervisor/kdesktop_lock_lockfile TQThreadInstance::start: Setting thread storage to 0x25b0130 [tdecore] Deleting stale lockfile /tmp/tde-supervisor/kdesktop_lock_lockfile TQThreadInstance::start: Setting thread storage to 0x1317e30 [tdecore] Deleting stale lockfile /tmp/tde-supervisor/kdesktop_lock_lockfile TQThreadInstance::start: Setting thread storage to 0x22511b0 [tdecore] Deleting stale lockfile /tmp/tde-supervisor/kdesktop_lock_lockfile TQThreadInstance::start: Setting thread storage to 0x1e2e000 [tdecore] Deleting stale lockfile /tmp/tde-supervisor/kdesktop_lock_lockfile TQThreadInstance::start: Setting thread storage to 0x155a100 [tdecore] Deleting stale lockfile /tmp/tde-supervisor/kdesktop_lock_lockfile TQThreadInstance::start: Setting thread storage to 0x806130 [tdecore] Deleting stale lockfile /tmp/tde-supervisor/kdesktop_lock_lockfile TQThreadInstance::start: Setting thread storage to 0x25d0080 [tdecore] Deleting stale lockfile /tmp/tde-supervisor/kdesktop_lock_lockfile TQThreadInstance::start: Setting thread storage to 0x1771300 Thanks,
