recognizes wirless WPA network, will not connect

[Wawesome]

I work at a student IT help center at a university in Montana. A girl has brought in her MAC 10.4 to try to connect to the universities wireless WPA network. All the settings are correct, for I connect laptops of all sorts for students everyday. The computer recognizes the network but will not bring up the "certificates" window so i can tell the computer to "always trust" the certificates. but it never comes up. i have tried deleting the Wireless profile and deleting the keychains for the WPA. And starting over from scratch, but the "Certificates" window still never shows. any ideas at all would greatly help

Have you ever seen this pop-up on a Mac before? No network I've ever connected to (edu or home or corporate) has ever asked to trust all certificates.
