Cannot login because the username/password is incorrect or cannot login because the login attempt is not displayed?

We also have a WLC 5508 in the DMZ and we cannot login by the Web or Console.

Would power-recycle it help ?

Recently we commission Prime and the consultant was hacking around to get it to work - not sure if this Prime is causing all the trouble here ?

Thanks

is the DMZ controller in an HA SSO configuration? If so, then the same rules apply: Web access and console access can only be achieved on the PRIMARY controller. I believe SSH access is allowed into the secondary controller.

No, it is stand-alone !
