Hello, I am trying to configure last-login plugin for dovecot 2.4.1 and
getting the following error.

doveconf -n

2.4.1-4 (7d8c0e5759): /etc/dovecot/dovecot.conf

Pigeonhole version 2.4.1-4 (0a86619f)

doveconf: Fatal: Error in configuration file
/etc/dovecot/conf.d/30-lastlogin.conf line 24: pattern: Unknown
setting: pattern (dict_map_key_field_pattern or
dict_map_key_field_service_pattern not found either.)

I am using the example config from the dovecot 2.4 documentation.
https://doc.dovecot.org/2.4.0/core/plugins/last_login.html#mysql-example

Is this a bug in the config parser or in the example config?

doveconf -n output with pattern lines in 30-lastlogin.conf commented:
