<title>The <filename>pool_hba.conf</filename> File</title>
<literal>pool_hba</literal> mechanism similar to the <literal>pg_hba</literal> mechanism for

+ The <filename>pool_passwd</filename> file manages passwords for
+ authentication used when clients connect
+ to <productname>Pgpool-II</productname>
+ (see <xref linkend="guc-pool-passwd"> for more details). The
+ passwords registered on <filename>pool_passwd</filename> must match
+ with the passwords registered
+ on <productname>PostgreSQL</productname>. Note that passwords
+ changed on <productname>PostgreSQL</productname> are not
+ automatically sync to the passwords
+ on <filename>pool_passwd</filename>. <link linkend="auth-scram">scram-shar-256
+ authentication</link> and <link linkend="auth-md5">MD5
+ authentication</link> require that the user name and the password
+ have been already registered on <filename>pool_passwd</filename>,
+ while <link linkend="auth-password">clear text password
+ authentication</link> does not require that. Therefore, if you want
+ to avoid maintaining the <filename>pool_passwd</filename>, it would
+ be worth to check <link linkend="auth-password">clear text password
+ authentication</link>.
