updated step 6.  Thanks to UBC for finding a glitch:  When the created_on field is left blank, it can cause an exception (java.sql.SQLException: Value '0000-00-00 00:00:00' can not be represented as java.sql.Timestamp).   The result is that the system admin permission does not get applied to that user.  So I updated the instructions to suggest putting in the current date instead of leaving blank.
