This is mostly for the record, as I found nobody else encountering this 
problem.

Interesting... the same thing on a FreeBSD 9.1-RELEASE-p6 gives a 
different result.  After getting into the jail via 'ezjail-admin 
console', there is a tty listed:

# w
7:14PM  up 43 days, 23:52, 1 user, load averages: 0.00, 0.00, 0.00
USER       TTY      FROM                      LOGIN@  IDLE WHAT
root       pts/0    -                         7:14PM     - w

And all is well:

# doveoveadm pw -s SHA512-CRYPT
Enter new password:
