Hi.

 

When we try connect to an ORACLE database via DATA MANAGEMENT STUDIO, the error "[DATAFLUX][ODBC Wire Protocol driver]ORA-28040: No matching authentication protocol" is displayed.

 

What will happen?

 

Thanks.

I can't explain why your getting that error but a quick search of our technical support tracks suggested the following possible resolutions:

 

1. Add the following lines to sqlnet.ora file on the server:

  • SQLNET.ALLOWED_LOGON_VERSION_SERVER=8
  • SQLNET.ALLOWED_LOGON_VERSION_CLIENT=8
  • Then restart Oracle TNS Listener

or

2. Use "DataFlux Oracle Driver" instead of the "DataFlux Oracle Wire Protocol Driver"
