Active Directory and Wi-Fi integration

Greetings,

Here is the issue that we are having:

We have a couple of users who are unable to connect to our Cisco WLAN 2704 using LDAP authentication. We have created a wifi group called Canada Wifi which users are added to when they need wifi access.

Troubleshooting completed:

1) Deleted and recreated user profile
2) Tested connectivity on other laptops

Both instances the user fails to connect due to a "user error".

RSOP shows the user is in the group that requires access. Also gpresult /R and gpresult /r /scope *computer* shows they are within the required groups.

Any help would be greatly appreciated.
