# ==== Purpose ====
#
# Reverts the changes done by rpl_priv_checks_user_configuration.inc
# This file is normally sourced by rpl_end.inc for replication use cases
# or gr_clear_configuration.inc for group replication use cases.
#
# ==== Usage ====
# [--let $rpl_change_topology_user_created= 1:rpl_applier_priv_user'@'localhost
#    2:rpl_applier_priv_user'@'localhost]
#  --source include/rpl_clear_priv_checks_user_configuration.inc
#
# Parameters:
#   $rpl_change_topology_user_created
#     Specifies the user account created for each server in format :
#     server_number1:user1, server_number2:user2 ...
#
