It looks like doveadm wants to do a > passdb lookup to find out which server should handle this user. Passdb > lookups don't work with LDAP binding. But if everything else works then I > think you simply shouldn't have enabled doveadm proxying. So, set > doveadm_proxy_port back to 0? thank you Timo, setting doveadm_proxy_port to 0 did the trick.
