Hello,
I am working on database server 12.2 and the OS is linux 64 bit. I am trying to connect to this database server using a .NET application running on a windows 64 bit machine with Oracle client 11.2.0 installed. It is failing with ORA-28040: No matching authentication protocol error.
What is the workaround to make this work?
Surfed the forums and internet for possible solution and we have tried setting the SQLNET.ALLOWED_LOGON_VERSION = 8 ,SQLNET.ALLOWED_LOGON_VERSION_CLIENT = 8 and SQLNET.ALLOWED_LOGON_VERSION_SERVER = 8 in both the server and client sqlnet.ora files with no success.
Please suggest the possible solutions to connect from oracle 11.2.0 client to Oracle database 12.2 server DB. Any help is appreciated.
Thanks a lot.
