[Pgpool-general] Problems with md5 mode

[Maria Antonia Lajus Marrero]

I need a PGPool configuration that guarantee security and safety,
because I've tried a configuration with "md5" and gives me error. I
can not restrict access to the databases in the cluster. Neither in
the PostgreSQL pg_hba.conf file or in the pgpool_hba.conf file of
pgPool-II.

This is the error:
MD5 authentication is unsupported in replication, master-slave and
parallel modes

Please answer me.
thank you very much
