802.1x machine & user authetication

When using CTA 2.1 with the 802.1x supplement, first the machine would authenticate upon boot up and then when the user logged in they would be re-authenticated and any particular user settings would be applied. This was all evident in the ACS logs.

However it seems when using native 802.1x on an XP machine w/ no CTA, first the machine authenticates but when the user logs in there is no re-authentication of the user. If I shutdown or disconnect the connected switch port and enable/re-connect it then the ACS logs show the user authentication taking place.

Is this by design of the native 802.1x implementations? And is there a way I can get it do the dual authentications (machine & user on log in) like it seemed to do with the 802.1x CTA?

You need to enable EAPOL-Starts on the machine.
