Dear Freeradius Hackers, This is new implementation. Can someone help me to troubleshoot why freeradius mysql authentication is failing. i have cross check every expect but still seem that something is not in place. What is i have done: installed Freeradius + MySQL Databases Configured Freeradius & Created MySQL Database. configured the following files: "sql.conf" "radiusd.conf" "default" enabled in radiusd.conf to "$INCLUDE = sql.conf" Radius is up and running without authentication even from localhost. Radius database is setup properly, no problem to start/stop "radiusd" radios_log are shown in section below. Results: tail -f "/var/log/radius/radius.log - Output Sat Dec 15 11:20:34 2012 : Info: rlm_sql (sql): Driver rlm_sql_mysql (module rlm_sql_mysql) loaded and linked Sat Dec 15 11:20:34 2012 : Info: rlm_sql (sql): Attempting to connect to radius@localhost:3306/radius Sat Dec 15 11:20:34 2012 : Info: rlm_sql (sql): Attempting to connect rlm_sql_mysql #0 Sat Dec 15 11:20:34 2012 : Info: rlm_sql_mysql: Starting connect to MySQL server for #0 Sat Dec 15 11:20:34 2012 : Info: rlm_sql (sql): Connected new DB handle, #0 Sat Dec 15 11:20:34 2012 : Info: rlm_sql (sql): Attempting to connect rlm_sql_mysql #1 Sat Dec 15 11:20:34 2012 : Info: rlm_sql_mysql: Starting connect to MySQL server for #1 Sat Dec 15 11:20:34 2012 : Info: rlm_sql (sql): Connected new DB handle, #1 Sat Dec 15 11:20:34 2012 : Info: rlm_sql (sql): Attempting to connect rlm_sql_mysql #2 Sat Dec 15 11:20:34 2012 : Info: rlm_sql_mysql: Starting connect to MySQL server for #2 Sat Dec 15 11:20:34 2012 : Info: rlm_sql (sql): Connected new DB handle, #2 Sat Dec 15 11:20:34 2012 : Info: rlm_sql (sql): Attempting to connect rlm_sql_mysql #3 Sat Dec 15 11:20:34 2012 : Info: rlm_sql_mysql: Starting connect to MySQL server for #3 Sat Dec 15 11:20:34 2012 : Info: rlm_sql (sql): Connected new DB handle, #3 Sat Dec 15 11:20:34 2012 : Info: rlm_sql (sql): Attempting to connect rlm_sql_mysql #4 Sat Dec 15 11:20:34 2012 : Info: rlm_sql_mysql: Starting connect to MySQL server for #4 Sat Dec 15 11:20:34 2012 : Info: rlm_sql (sql): Connected new DB handle, #4 Sat Dec 15 11:20:34 2012 : Info: Loaded virtual server <default> Sat Dec 15 11:20:34 2012 : Info: Loaded virtual server inner-tunnel Sat Dec 15 11:20:34 2012 : Info: ... adding new socket proxy address * port 32959 Sat Dec 15 11:20:34 2012 : Info: Ready to process requests. ========================================================================= Output of "radiusd -X" ... adding new socket proxy address * port 51412 Listening on authentication address * port 1812 Listening on accounting address * port 1813 Listening on command file /var/run/radiusd/radiusd.sock Listening on authentication address 127.0.0.1 port 18120 as server inner-tunnel Listening on proxy address * port 1814 Ready to process requests. ======================================================================== Command to Check the radius Authentication: radtest mark mypassword localhost 1812 99THi49UGotool Output: Sending Access-Request of id 48 to 41.171.71.61 port 1812 User-Name = "mark" User-Password = "radmin" NAS-IP-Address = 192.168.3.106 NAS-Port = 100 Message-Authenticator = 0x00000000000000000000000000000000 ====================================================================== Two MySQL Radius Users PAY attention to the field "OP" (:= & ==) But auth is not working for any user. mysql> select * from radcheck where UserName='mark'; +----+----------+-----------+----+-----------------+ | id | UserName | Attribute | op | Value | +----+----------+-----------+----+-----------------+ | 3 | mark | radmin | := | 99THi49UGotool | +----+----------+-----------+----+-----------------+ 1 row in set (0.00 sec) mysql> select * from radcheck where UserName='dany'; +----+----------+-----------+----+-----------------+ | id | UserName | Attribute | op | Value | +----+----------+-----------+----+-----------------+ | 1 | dany | badmin | == | 99THi49UGotool | +----+----------+-----------+----+-----------------+ radius is up and running without authentication "== or :=" make no difference none of the user can authenticate. ============================================ selinux off freeradius is up mysql db is up there are two database users why auth would be failing?
