# Static passdb. Included from 10-auth.conf.

# This can be used for situations where Dovecot doesn't need to verify the
# username or the password, or if there is a single password for all users:
#
#  - proxy frontend, where the backend verifies the password
#  - proxy backend, where the frontend already verified the password
#  - authentication with SSL certificates
