Hi Patrick,

Are you using the latest version of the WP Shib plugin? It now
sanitizes names order to deal with the @ problem. We're using it to
allow integration with our existing login systems, and not (yet) for
off-campus logins, but if the problem you're having is just the name
syntax that shouldn't make a difference. There are some details here:
(note that that thread is about broken links, but it gets into user
name rewriting further down the thread).

best of luck,
