Director/Doveadm: Trying to iterate users, but userdbs don't support it

Hi

I'm doing: doveadm force-resync -S director1:1234 -A "*"

The director gives this error:

Jul 06 16:17:29 auth: Error: Trying to iterate users, but userdbs don't support it Jul 06 16:17:29 doveadm: Error: User listing returned failure Jul 06 16:17:29 doveadm: Error: Failed to iterate through some users

The director has "iterate_query" set
