Hi I am new user of freeradius . I want to connect FreeIPA server to radius server to make WiFi authentication . I have tried to connect them by Kerberos I use what mention in this link : http://freeradius.1045715.n5.nabble.com/Freeradius-3-0-4-authentication-to-F... but if I use radtest this logs will show : Sent from Mail for Windows 10 (0) Received Access-Request Id 193 from 192.168.205.7:44657 to 192.168.205.7:1812 length 75 (0) User-Name = "admin" (0) User-Password = "Password@" (0) NAS-IP-Address = 192.168.205.7 (0) NAS-Port = 1812 (0) Message-Authenticator = 0xd557b8133468b6cdb1449306dac7fbf5 (0) # Executing section authorize from file /etc/raddb/sites-enabled/default (0) authorize { (0) policy filter_username { (0) if (&User-Name) { (0) if (&User-Name) -> TRUE (0) if (&User-Name) { (0) if (&User-Name =~ / /) { (0) if (&User-Name =~ / /) -> FALSE (0) if (&User-Name =~ /@[^@]*@/ ) { (0) if (&User-Name =~ /@[^@]*@/ ) -> FALSE (0) if (&User-Name =~ /\.\./ ) { (0) if (&User-Name =~ /\.\./ ) -> FALSE (0) if ((&User-Name =~ /@/) && (&User-Name !~ /@(.+)\.(.+)$/)) { (0) if ((&User-Name =~ /@/) && (&User-Name !~ /@(.+)\.(.+)$/)) -> FALSE (0) if (&User-Name =~ /\.$/) { (0) if (&User-Name =~ /\.$/) -> FALSE (0) if (&User-Name =~ /@\./) { (0) if (&User-Name =~ /@\./) -> FALSE (0) } # if (&User-Name) = notfound (0) } # policy filter_username = notfound (0) [preprocess] = ok (0) [chap] = noop (0) [mschap] = noop (0) [digest] = noop (0) suffix: Checking for suffix after "@" (0) suffix: No '@' in User-Name = "admin", looking up realm NULL (0) suffix: No such realm "NULL" (0) [suffix] = noop (0) eap: No EAP-Message, not doing EAP (0) [eap] = noop (0) [files] = noop rlm_ldap (ldap): Reserved connection (0) (0) ldap: EXPAND (uid=%{%{Stripped-User-Name}:-%{User-Name}}) (0) ldap: --> (uid=admin) (0) ldap: Performing search in "cn=users,cn=accounts,dc=exalt,dc=ps" with filter "(uid=admin)", scope "sub" (0) ldap: Waiting for search result...
