Hi Guys, i have a problem with 3.0.12 and User-Name. I send a request with domain name included in User-Name: radtest -t mschap "test\radius" radius localhost 1 testing123 On freeradius i see User-Name = "test\radius" in line 2. (0) Received Access-Request Id 61 from 127.0.0.1:34351 to 127.0.0.1:1812 length 142 (0) User-Name = "test\radius" (0) NAS-IP-Address = 10.100.254.174 (0) NAS-Port = 1 (0) Message-Authenticator = 0xdd90f7f9365aca2896632b1a531bb760 (0) Framed-Protocol = PPP (0) MS-CHAP-Challenge = 0xe7d0a3bb2ba11619 (0) MS-CHAP-Response = 0x0001000000000000000000000000000000000000000000000000f16973c17df493cec36e7f24c5ed837697dbb69248fdb117 (0) # Executing section authorize from file /etc/freeradius/sites-enabled/default (0) authorize { (0) [preprocess] = ok (0) ntdomain: Checking for prefix before "\" (0) ntdomain: No '\' in User-Name = "test adius", looking up realm NULL (0) ntdomain: No such realm "NULL" ... But for ntdomain the User-Name is broken. The blackslash escape the "r" so i seed "test adius" instead "test\radius". I also tried to use split_username_nai but here the same problem. My problem is, that windows send every time a domain. Anybody have an idea to fix this bug? Greets Marco
