Thank you for the pointers. Am I right to interpret the Dovecot docs as
stating that SSHA384 is not supported by the official packages, and that
my only recourse might be building from the source code and adding some
external code in the process?

I do not remember encountering SSHA384 before, but the existing LDAP
records use this schema for about half of a huge user base. Telling all
affected users to change their passwords is not an option.
