ISSUE:       5368
TITLE:       Server does not validate correctness of user/password pair provided in EXECUTE STATEMENT operator
DESCRIPTION:
  Confirmed on build 32136 (RC1), build 32181: wrongly displayed names of non-existent user 'TMP$C5082'
  and user SYDSDBA that login was provided with wrong (but NOT empty) password.
  NOTE: check does NOT perform inside ES when password is empty string or any number of ascii_char(32)
  and 'new' user specified is equal to user name that was used to login - see examples here when password
  for SYSDBA is '' or ascii_char(32).
NOTES:
[06.02.2019] added separate code for 4.0 because of new error message ("Missing security context for ...")
JIRA:        CORE-5082
