I would like to know how the Nac Server fallback feature works in an OOB deployment.

The documentation says that there three option (ignore, allow all, block all).

Whe you have the allow all option enable, does the NAC put the user in an access vlan or the user just access to the network through the authentication VLAN?

Assuming the CAM has failed, the CAS would allow all traffic from the AUTH VLAN to the ACCESS VLAN. Since the CAM has failed, the switchports which are not in the AUTH VLAN would behave per the rules/ACLs on the VLAN they're in and won't get flipped over.
