[xwiki-users] kerberos SSO -> strip domainname from username

Hi all,   I have configured xwiki with LDAP authentication and kerberos SSO. When I use a browser without automatic Kerberos SSO, I get a keberos login page. When I fill in username and password manually it works great. But when I set the browser to use automatic logon, I get the xwiki login page! (at least in FireFox, IE says “cannot show page”) I get the same results when I manually login with “username@DOMAIN” and “password”.  So I think the domain part is used in the automatic logon. (and is the actual problem…)   I see there is java code that strips the @DOMAIN part from the username. But I have no idea how or where to implement this. I hope some can help me!   Mark
