I've got no 32 bit driver. sslmode makes no difference. However, I've restarted Hana and now it at least responds to changes in the .odbc.ini. It writes
SAP DBTech JDBC: [403]: internal error: Cannot get remote source objects: c
and when I comment out the driver line, it writes again Data source not found. Unfortunately, it ignores the trace directive, so I cannot see what the problem is, the 'c' looks like an erased message.
