We've done JS and server side. I don't think it matters for Shibboleth, 
but we also had issues in the past where the username coming out of CAS 
was cased to how the user typed it.

         function removeDomainFromUsername() {
                 var usernameField = document.getElementById("username");
                 var username = usernameField.value;
                 var handle = username.substring(0, 
username.lastIndexOf("@"));
                 if (handle.length > 0) {
                         usernameField.value = handle;
                 }
         }
<input autofocus class="form-element form-field" id="username" 
name="j_username" onBlur="removeDomainFromUsername();" type="text"
value="#if($username)$encoder.encodeForHTML($username)#end">



     <!-- Apply any regular expression replacement pairs before 
validation. -->
     <util:list id="shibboleth.authn.Password.Transforms">
         <!-- Get the right username -->
         <bean parent="shibboleth.Pair" p:first="^(.+)@.*$" p:second="$1" />
     </util:list>


We really don't care what domain you put in, we just want it to drop it 
off. Given that about half of the systems require a domain, and other 
other half require that the domain is missing, we figured it was good to 
make these work no matter what your muscle memory does.

Unfortunately, this doesn't handle leading or trailing whitespace. Going 
to have to figure out how and where to take care of that. Autocomplete 
from keyboards can end up putting that in, and it is frustrating when 
that isn't handled.
