Hello, Has anyone had any experience with Radius and Oracle? I am having an issue getting Oracle and Radius to communicate correctly. I have Oracle 10G installed on RHEL Linux 4 ES and also have Radius installed on the same server. Radius is in turn connecting to LDAP and I verified using the radtest and radclient utilities that there is a successful connection and authentication between Radius and LDAP. I have verified using the adapters command that the Radius adapters are installed for Oracle. I have created a user identified externally and granted connect and resource and when I attempt to connect I get an invalid id/password error...although when using the radius test utilities with the same password it works. I have verified that the remote_os_auth=false and os_authent_prefix= " ". When I attempt an Oracle Sqlplus connection using the id I created the Radius server log has this message: "WARNING: Unprintable characters in the password. ? Double-check the shared secret on the server and the NAS!" I have verified the "secret" on the Radius server in the clients.conf matches the data in the radius.key file on the Oracle Server and I used netmgr to create the the sqlnet.ora file and it has: SQLNET.RADIUS_AUTHENTICATION = <correct ip address> SQLNET.RADIUS_AUTHENTICATION_PORT = 1812 SQLNET.RADIUS_SECRET = /u01/app/oracle/product/10.2.0/RACF2/network/security/radius.key SQLNET.RADIUS_AUTHENTICATION_TIMEOUT = 10 SQLNET.AUTHENTICATION_SERVICES= (BEQ, TCPS, RADIUS, NTS) NAMES.DIRECTORY_PATH= (TNSNAMES, EZCONNECT) Looking at a trace file the lines that stand out are: [08-JUN-2007 15:55:51:153] nspsend: 00 00 35 4F 52 41 2D 32 |..5ORA-2| [08-JUN-2007 15:55:51:153] nspsend: 38 30 33 35 3A 20 43 61 |8035:.Ca| [08-JUN-2007 15:55:51:153] nspsend: 6E 6E 6F 74 20 47 65 74 |nnot.Get| [08-JUN-2007 15:55:51:153] nspsend: 20 53 65 73 73 69 6F 6E |.Session| [08-JUN-2007 15:55:51:153] nspsend: 20 4B 65 79 20 66 6F 72 |.Key.for| [08-JUN-2007 15:55:51:153] nspsend: 20 41 75 74 68 65 6E 74 |.Authent| [08-JUN-2007 15:55:51:153] nspsend: 69 63 61 74 69 6F 6E 0A |ication.| Which seems to indicate a problem getting the radius.key value, I think... I have already opened a TAR with Oracle support however after over 3 weeks with out any solutions I thought I would pursue other avenues... Any ideas or suggestions would be greatly appreciated. thx Marc
