ORA-28040: No matching authentication protocol Oracle

I am trying to connect oracle12C but not able to connect .

i have tried with previous answer : ORA-28040: No matching authentication protocol : Oracle 12c Upgrade?

using ojdbc6.jar . But it is not worked

Next i have 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.

After Lot of debug ,

Oracle 12c comes all its older version . If you have installed 11g client first upgrade to 12c . Then all set up need to done . Net manager wont throw ORA-28040: No matching authentication protocol Oracle error and will pass successfully .
