The design is that we get a replication event with a blank password in
it, causing the password to be wiped locally.  That triggers the next
login to go via the master DC which if successful triggers a async
replication of the new password.

So, it is meant to be safe for password change/reset, and there are
tests for this.

Thanks for asking!
