The release notes state that the OS is changing from Fedora to CentOS 5.3 in version 4.7 of NAC.
The means to upgrade one must create an ISO boot disk and install the latest version of software.(In order to boot the new OS kernel.)
Does this mean we are at the end-of-the line with version 4.6?
Thank you in advance.
Doesn't really matter. Doing CAS first saves you an extra reboot, so you can do that first.
For AD 2k3 SSO, use the 5.2.3790.0 version. Download here: http://www.employees.org/~basti/ktpass.zip
You're not required to wipe out the existing setup to upgrade to 4.7. Yes, you do have to boot from a CD, but you're given the option to upgrade or reimage from the boot prompt.
Choose upgrade and your existing setup will remain.
