# This test checks the server default user for the SQL session server is not
# affected by GR, and GR fails when it is not there.
#
# Test:
# 0. The test requires one server.
#  - Install plugin at startup.
# 1. On server assert check the GR user 'mysql.session' exists after install.
# 2. Bootstrap start a group. Assert check the GR user 'mysql.session' exists.
# 3. Drop the user. Bootstrap start GR and check the start fails
# 4. Uninstall the plugin and verify that user is still there
# 5. Cleanup
