# The user must have GROUP_REPLICATION_ADMIN privileges to modify the group's
# "communication protocol."
#
# Test:
#   0. One server is enough for this test
#   1. Create user without GROUP_REPLICATION_ADMIN privileges
#   2. Connect to server using under-privileged user
#   3. Modifying the group's "communication protocol" should fail due to lack of
#      privileges
#   4. Cleanup
