    I have a C++ application trying to connect to an Oracle8 database using an ODBC DSN. The connection fails showing the following error : 'TNS-12640 - Authentication adapter initialization failed' . Do you know any reason why I would get a message like that?

    Cause: The function specified in the authentication table entry for the service failed.

    Action: Enable tracing to determine the exact error.


    Does that mean anything to you?

    well , I didnt see this error before , but the metalink expert says ..

    either remove or change the value of the parameter
    sqlnet.authentication_services

    you can find this one in the sqlnet.ora
    $ORACLE_HOME/network/admin/sqlnet.ora

    you can set the sqlnet.authentication_services=NONE or comment this line .

    That should work ( ?? )
