DOT1.X authentication with ACS and Active Directory

[dbertinetti]

If I log on to the network the first time,the authentication works Good, but when other user log on

to the network without restart the host,then it does't work.Then,if I restart de notebook the authenticacion work's good again.

The 802.1x protocol does not realize of the user change.

Someone know this problems?.Like doing that reauthenticate the user without having to bootear the PC??

Thanks in advance

What supplicant is at work here, and have these users ever logged onto the machine before?

Do you have machine auth enabled?
