I've been pulling my hair out with this one. I have a Cisco 2504 WLC that is configured to authenticate against my 2008 R2 domain controller with Network Policy Server. I have my CA and certs in order, successfully deployed my wireless profile through a test Group Policy, and verified that everything does indeed work. My test laptop successfully joins the wireless network. My configuration allows joining the wireless network prior to user login. I've verified that it is working fine (I've also verified that it will deny access if the wrong credentials are given). I'm still logging a ton of errors on both my WLC and the domain controller. I'm not sure they are anything to worry about, but I'm trying to get any kinks worked out before deploying to my test users.
Here are the errors:
WLC:
