Consoled into a 9800 today, created a new user, then logged into the GUI and did the Day 0 configuration. Reconnected to the GUI and was able to do a good bit of the configuration from there; I also tried to ssh to the WLC and enter some configuration, but even though "enable" was listed when I entered "?" at the > prompt, when I try to enter it was a command I get a message "Error in Authentication". I was able to use the CLI portion of the GUI to enter the configuration I needed to, but wanted to see if there was a reason for response and being unable to get into the CLI.

From GUI you are able to use CLI, so post-show run here (check anything changed on the vty lines)
how about ssh ?

Looking at the exported configuration I think I see the issue. During the Day 0 wizard I added a Radius server that I intended to use for 802.1x for 1 of the WLANs but I think the controller also might be using that for logins as well. Shouldn't the controller fail-back to local authentication if the server isn't reachable or isn't responding (I put in a dummy password during the wizard).

yes it should if configured correctly AAA with radius and local- (since we are dark on the config - I am afraid to comment)

I was able to figure this out; was just missing an enable password. Once I added that the command took and I was able to get into privileged mode from cli.
