User authentication using local file

OS environment:

Linux qnap-nas 5.10.60-qnap #1 SMP Thu Jan 12 04:39:10 CST 2023 x86_64 GNU/Linux

I enabled  "auth-passwdfile.conf.ext? in 10-auth.conf
#!include auth-deny.conf.ext
#!include auth-master.conf.ext
#!include auth-system.conf.ext
#!include auth-sql.conf.ext
#!include auth-ldap.conf.ext
!include auth-passwdfile.conf.ext
#!include auth-checkpassword.conf.ext
#!include auth-static.conf.ext

In this file I have following entries and I don?t know what to enter for userdb

passdb {
  driver = passwd-file
  args = /opt/local/etc/dovecot/users
}

userdb {
  driver = passwd-file
  #args = username_format=%u /opt/local/etc/dovecot/users

  # Default fields that can be overridden by passwd-file
  #default_fields = quota_rule=*:storage=1G

  # Override fields from passwd-file
  #override_fields = home=/home/virtual/%u
}

In the users file I have 2 users defined as follow:
user1:{SSHA512}<encrypted password>::::::
user2:{SSHA512}<encrypted password::::::

Dovecot gives following error message on startup:
Mar 23 08:50:30 master: Info: Dovecot v2.3.20 (80a5ac675d) starting up for imap,
lmtp, sieve (core dumps disabled)
Mar 23 08:50:30 auth: Debug: Loading modules from directory:
/opt/local/lib/dovecot/auth
Mar 23 08:50:30 auth: Debug: Module loaded:
/opt/local/lib/dovecot/auth/lib20_auth_var_expand_crypt.so
Mar 23 08:50:30 auth: Fatal: userdb passwd-file: Missing args

I don?t know what arguments I have to enter for userdb
