Hi, Recently, I found the wrong realm in the detail files. This log is captured from detail file. Tue May 8 17:46:41 2007 Class = 0x417074696c6f313a313a31383030 User-Name = "ABC/950160@def.org" Acct-Status-Type = Start Acct-Session-Id = "464046fecc9c08a5" Acct-Delay-Time = 0 Acct-Authentic = RADIUS Framed-IP-Address = <Encrypted> NAS-IP-Address = <Encrypted> NAS-Port-Type = Wireless-802.11 Event-Timestamp = "May 8 2007 17:46:41 CST" NAS-Identifier = "NAS" Vendor-13209-Attr-9 = 0x5157464e484150433037 Called-Station-Id = <Encrypted> Calling-Station-Id = <Encrypted> Vendor-13209-Attr-1 = 0x5177617265507562537461726275636b73 NAS-Port-Id = "NAS-Port" WISPr-Location-ID = <Encrypted> WISPr-Location-Name = <Encrypted> Proxy-State = 0x30 Client-IP-Address = <Encrypted> Acct-Unique-Session-Id = "26719654223287c6" Stripped-User-Name = "ABC/950160" Realm = "def.org" Freeradius-Proxied-To = <Encrypted> Timestamp = 1178617601 I configured two realm in proxy.conf. One is realm "ABC" (prefix mode), and another is "def.org" (suffix mode). In my thinking, when request come into radius, prefix will work first then suffix. (configured in radius.conf) In this case, I should have a realm value "ABC" and Stripped-User-Name value "950160@def.org". But I got the realm value "def.org" and Stripped-User-Name value "ABC/950160". Is it a bug ? or some configuration I missed. PS. I'm using freeradius-1.1.2. Thanks. Rio
