# Verify that login, logout, and login failure events are properly stored in system.session_log
# when different `IDENTIFIED BY` clauses are used on user.
#
# Make sure that system.session_log entries are non-empty and provide enough info on each event.
#
# Using multiple protocols
# * native TCP protocol with CH client
# * HTTP with CURL
# * MySQL - CH server accesses itself via mysql table function.
# * PostgreSQL - CH server accesses itself via postgresql table function, but can't execute query (No LOGIN SUCCESS entry).
# * gRPC - not done yet
#
# There is way to control how many time a query (e.g. via mysql table function) is retried
# and hence variable number of records in session_log. To mitigate this and simplify final query,
# each auth_type is tested for separate user. That way SELECT DISTINCT doesn't exclude log entries
# from different cases.
#
# All created users added to the ALL_USERNAMES and later cleaned up.
