JDBC Gateway connecting to DB2.

Resolving the problem

Check what you have the database authentication set to:

db2 get dbm cfg | grep AUTHENTICATION

If it is correctly set, this value should be SERVER. You can reset it as

db2 update dbm cfg using authentication server

Please verify this action with your DBA however before applying the
change to the database.
