Until the late 2010s, the AD account password at my financial institution employer was capped at 12 characters because, for a subset of workers, AD creds were sync'ed to a mainframe application that could only support that many characters.

Sounds about right. One of Australia's big four banks had the online banking password requirement of exactly six characters for a long time - for similar reasons I assume.
