dot1x - Computer Authentication not working

Wired users.

When PC boots up and tries to perform "computer authentication" with ACS and then Win2003 AD, I get the following error:

"External DB user invalid or bad password"

Thanks

Re: dot1x - Computer Authentication not working

Check for the failed attempt does it display this format:

host/

Check in the Auth.log for the same time range as in the Failed Attempt.

Is the computer part of the same domain as the ACS?

Yes, host/, and the PC is in the same domain

As ACS. ACS is a domain member not domain controller.

I have also added the computer account "CISCO" in AD.

Looking at the logs looks like communication issue with AD.

Re: dot1x - Computer Authentication not working

Make sure the integration of AD and ACS is done perfectly.Verify the user authentication by using a valid user account from AD on any of the device such as Switch or Router.

Make a checklist of step wise procedure and be sure no single step was missed during integrating AD and ACS
