rlm_realm doesn't strip the username

Hi, <http://www.freeradius.org/list/users.html> I am using radius version 2.0.0-pre0. I have the following problem that when I receive the Accounting-Request with the username whose domain part is not checked with any of my realm defined in the proxy.conf file. The username is not stripped. I use the suffix rule for domain: 'username@domain" in my realm module and I inoke it in preacct in radiusd.conf. I have the DEFAULT realm defined and it doesn't have the nostrip option activated. So I think when there is no domain match the username should also be stripped?? I kindly ask for your support. Wait forward for your feedback Best regards Tomasz
