NAC OOB Windows SSO help

[gwilliams59]

We just upgraded from Windows 2003 AD to Win2k8 R2 and Single Sign on has stopped working. Authentication works fine, but the NAC agent does not use the Windows credentails. Users have to enter thier username and password manually.

The AD server is a new server but has the same IP addresses as the old one. I am running CAM/CAS 4.7.2.

Gregg,

2k8 doesn't do DES by default, so I suspect that's where it's failing. Please look at the following sections and rerun ktpass (on a new user preferably) as detailed in the link:

HTH,
