Anyone encountered the same problem with Yosemite?

I upgraded the Mac from Mavericks to Yosemite and then i encountered this.

Appreciate any help. Thanks

Got it. So there's an error with the wifi authentication. Does it do the same with Ethernet connected?

Are you using a profile to apply wifi authentication at the login window?

hi david,

i am not too sure if it's wifi authentication issue but seems a problem with the os after yosemite upgrade from mavericks.

i already removed the jamf binary and profiles but there still no input for username and password.

Ah I see. I haven't seen this issue at any of the sites I've been working at I'm afraid.

It could be worth looking at certificates in the keychain as that might be related.

Does it only do this on the Staff SSID?
