NAC ADSSO with NAC Module isn't working for all modules

Question

Hello,
We have a NAC OOB-L2-VG Deployment at the Central Site with VLAN Mapping and ADSSO which works just fine.
As part of the project we have implemented NAC Modules on ISR routers for the branch offices; same topology but as the documentation states no VLAN mapping was configured. The problem is that for some users in one branch office the ADSSO isn't working and in another branch office the ADSSO isn't working at all, all the users are getting authenticated with a local user we defined on the servers.
The configuration in both modules is exactly the same; they are using the same user to access the AD (the one used on the ktpass) the data links to the central site are both 1 Mbps and everything is pretty much the same thing.
I have checked the logs on the CAS-Module and it states that Windows SSO is running:
Nov 27, 2009 10:08:23 AM com.perfigo.wlan.jmx.admin.GSSRetrier$RetrierTask run
INFO: GSSR - Windows SSO is running
The interesting thing is that when the user goes thru the NAC process I see these logs:

FINE: Number of providers=1
The IP address 172.19.5.11 is the IP of the PC during the unauthenticated role; what the user is finally seeing is the CCA Agent asking for user and password instead of using the ADSSO.
The version of the Agent is 4.1.10, the NAS and NAM are running 4.1.8 and the only ackword thing is that the Active Directory Servers are running Windows 2000 SP4.
Any assistance would be much appreciated.
Thanks,
DL.
