My 802.1X Authentication fails repeatedly, and for no apparent reason.

Question

I'm a student at university, and my campus uses WPA2 Enterprise wireless in which we have to enter our central user name and password. I work for the campus tech help desk, and I've tried every possible password and have configured the wireless countless times, and I'm starting to think it's a more serious problem. Thing is, I've connected for at least a year now, and just in the past few weeks it started to refuse. First, here's the unhelpful error message I receive:
"802.1X is unable to authenticate. It is possible that the configuration you have provided is invalid. If you are unsure about what configuration to connect with, check with your network administrator.
( Error: 1 on port en1 )"
And just in case, here's the directions for setting up wireless on campus, which worked perfectly for me before: http://www.uc.edu/ucit/access/wpa2instructionsv2.html
I've done all I can think of at this point. I keep editing the wireless in and out of the "preferred networks," I even went into my system library and removed all of it manually and tried again, but no luck. Google searching yields nothing useful. Please, if anyone could give me some advice, I'd appreciate it.

Answer 1

In the off chance that anyone from the UC campus also comes here and looks at this problem.
There is currently an authentication problem with the campus WPA2 network related to Central login. If you have recently updated your password (as it forces you to do about every 3 months) then the new password is not being verified for use with the wireless network. This wouldn't be that big of a problem, but it also kicks out the user's old password... leaving the user unable to connect.
