802.1x machine & user authetication

Answered Question
Mar 13th, 2009

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?

I have this problem too.
