While using LDAP-based authentication, I have come across the message auth: Error: [...] Unknown scheme SSHA384
Based on the docs at [1] I use the dovecot.org packages provided for Ubuntu 20.04 LTS which, as you can see, are not yet documented in the HTML page, put are available via [2]. Specifically, I used apt-get install dovecot-ldap dovecot-sqlite to install Dovecot. What else is needed beyond the two listed packages in order to enable support for SSHA384 password hashes in Dovecot? Am I perhaps missing some required configuration parameter? Your help is appreciated. -Ralph [1] https://doc.dovecot.org/installation_guide/dovecot_community_repositories/ubuntu_packages/ [2] http://repo.dovecot.org/ce-2.3-latest/ubuntu/focal/
