Hi,
recently I have migrated our prevoius dovecot-lda to 2.2 with director + lmtp.
And we are having some issues. When lmtp delivers to ldap uid names everything works except sieve vacation (login is not found in headers so reply is not sent).
When using full email addresses in rcpt to vacation works but usernames are inconsistent (one user can login using his email address, or aliases, or uid). To fix that in ldap settings a have added uid=user which should be setting the username to approperate values.
Most of the times it works but some deliveries are using email addresses not ldap uid's which seems to break dict quota's. It's must be related to auth cache (flushing the cache fixes the issue temporarly for given account). I think that the cache can be "polluted" by some other dovecot service.
Does anyone have an idea where this can be comming from ?
doveadm auth lookup -f user mon@test.com returns expected ldap uid no email address
Thanks in advance for any help.

director is doing the authorization and passing it to the backend using a master user
