Strange CSM issue

[s-eastman]

I've having an issue whereby numerous failed authentication attempts to firewall devices are appearing in my ACS server, and originating from my CSM server, although the devices have been deleted from CSM. The username appearing ACS is "null" for some attempts and a valid userid for others. The CSM server is Windows based and CSM isn't integrated with ACS. Has anyone encountered this before?

Thanks,

sam

Before you can begin to import devices into Cisco Security Manger, you must first configure each device as an AAA client in your Cisco Secure ACS. In addition, you must configure the CiscoWorks/Security Manager server as an AAA client.
