I have NAC configured and running in an OOB deployment using Window SSO. Most users authenticate into their computers and then NAC does the login and posture assessment using SSO and those credentials.
We have a few users that have the Clean Access Agent pop up and ask them to enter a username, password and role. They can successfully log in using the same username and password that was used to log into the computer and domain. I have not been able to figure out why SSO does not work for them.
I have one user specifically that has the above problem, but can log in through SSO on another system without a problem. Other users can also log in successfully using SSO on the same PC that this user has problems with.
I am wondering if anybody has an idea what is causing this behavoir? I suspect that something is cached in that users temp files that is causing the problem, but I have not found anything.
We are running:
NAC OOB Clean Access Server version 4.6.1
NAC Agent version 188.8.131.52
