ORA-28040: No matching authentication protocol exception

I am trying to connect my grails project to Oracle databse(Oracle 12c) in windows(8) system. However, whenever I run my application I get following exception :

Caused by: org.apache.commons.dbcp.SQLNestedException:  Cannot create PoolableConnectionFactory (ORA-28040:  No matching authentication protocol)  Caused by:  java.sql.SQLException: ORA-28040:  No matching authentication protocol 

According to internet suggestion I also tried editing my *.ora file but it is not working.

I added following snippet in sqlnet.ora file :

SQLNET.ALLOWED_LOGON_VERSION=10 SQLNET.ALLOWED_LOGON_VERSION_CLIENT=10 SQLNET.ALLOWED_LOGON_VERSION_SERVER=10 

Here i tried assigning (10,11,12) but neither of them is working.

Can anyone please help me with this ?

What is Sqlnet Allowed_logon_version?

SQLNET.ALLOWED_LOGON_VERSION = 10. If the parameter does not exist, this is a Finding. If the parameter is not set to a value of 10 or higher, this is a Finding. NOTE: It has been reported that the there is an Oracle bug (6051243) that prevents connections to the DBMS using JDBC THIN drivers when this parameter is set.

I deleted the ojdbc14.jar file and used ojdbc6.jar instead and it worked for me
