Cisco 1131 LWAPPs associating with wrong controller - how to fix?

Cisco 1131 LWAPPs associating with wrong controller - how to fix?

Cisco 1131 LWAPPs associating with wrong controller - how to fix?

We've got 3 or 4 different sites that we've setup with LAPs (Cisco 1131), and configured option 43 on the DHCP scope for those sites to associate them with the controller they want to go to.

None of these have ever wanted to associate with the controller, almost as if they're not seeing anything from the option 43 configuration.

When option 43 is removed from the scope, and the LAP is rebooted, they pick up the DNS for CISCO-LWAPP-CONTROLLER and end up associating to the controller that the DNS entry points to.

After this has happened, we're not able to configure their primary/secondary controller, and get them talking to where they need to.

Does anyone know of a way to get these to associate to the primary controller?  Is there a way to manually configure this from the console?
