is this true? does it mean that i should have something like this in 
access to attr=uid,homeDirectory,uidNumber
        by anonymous read

still it does not work and i have in log files:

dovecot: auth(default): ldap(wojtek, user search: 
base=ou=Users,dc=frontline scope=subtree 
dovecot: auth(default): ldap(wojtek, Authenticated user 
not found
dovecot: auth(default): userdb(wojtek, user not found 
from userdb
dovecot: auth(default): master out: NOTFOUND^I4

to be honest i do not know how to make ldap searchable for anonymous 
user. i have tried several options and it does not work.

yes. could you please send config please both dovecot 
(/etc/dovecot/dovecot*.conf) and openldap (/etc/ldap/*.conf)

how would you recommend to sniff?

interesting thing. i also changed auth_bind to no dn and dnpass supplied 
and it does not work. looks like dovecot still tries to bind to ldap 
using anonymous user.

cheers, Wojtek
