Cause
Resolution
This is supported via Oracle's concept of reauthentication. The Oracle user needs to be granted CONNECT THROUGH privilege for the other user and as a result, the driver will authenticate with one user who has passed their credentials and if successful, switch the user context to the other user so you are effectively acting as the second user without having passed the second user's login credentials.

The JDBC driver supports this through the proprietary setCurrentUser method that we added to our ExtConnection interface. To use the fuctionality the application code would need to cast the JDBC Connection object to an ExtConnection and then call the setCurrentUser("userName") method. This method implementation does NOT require/support the specification of a password.

For additional information refer to the driver documentation, specifically the sections on "Reauthentication" and "ExtConnection interface (void setCurrentUser(String))"
