# MDEV-9614 Roles and Users Longer than 6 characters
#
# This test case checks the edge case presented in the MDEV. The
# real issue is actually apparent when the username is longer than the
# rolename.
#
# We need a separate database not including test or test_% names. Due to
# default privileges given on these databases.
#
DROP DATABASE IF EXISTS `bug_db`;
Warnings:
Note 1008 Can't drop database 'bug_db'; database doesn't exist

# The first user did not show the bug as john's length is smaller
# than client. The bug is apparent most of the time for usertestjohn.
