When i try to connect to Oracle 9i db, i get always ORA-1017 invalid username/password; logon denied. On Oracle 10g or higher all is well.
ODP.NET Core: 2.18.3; ASP.NET Core: 2.1.403
ConnectionString: "Data Source=myTnsName;password=myPassword;user id=myUserId"
TnsAdmin is set.
In Oracle log on db side i found this entry: ORA-1017 invalid username/password; Unknown Auth type: 6A
Any ideas are welcome? It is possible to connect?
