postfix ldap unknown user

[Jean-François Sénéchal]

Hi,

My config dovecot 2.2.13 Postfix 2.9.6 Debian wheezy

When I send a message to my user test (siroco) postfix said unknown user

But the user exist :

doveadm user siroco :
field    value
uid    3002
gid    2000
home    /var/spool/dovecot/mail/s/siroco
mail    maildir:~/Maildir:LAYOUT=fs

postmap -vq siroco ldap:/etc/postfix/ldap_virtual_aliases.cf
return siroco

2 questions :

postfix search with siroco or with siroco at citoyens2015.marche.be ?

postmap must return siroco or siroco at citoyen2015.marche.be ?

And I don't know if I set for alias_maps, virtual_mailbox_maps, 
virtual_alias_maps ?

My postconf

alias_database = hash:/etc/aliases
alias_maps = hash:/etc/aliases, ldap:/etc/postfix/ldap-citoyen.cf
append_dot_mydomain = no
biff = no
config_directory = /etc/postfix
inet_interfaces = 172.17.1.232, 127.0.0.1
mailbox_command = procmail -a "$EXTENSION"
mailbox_size_limit = 0
mydestination = $myhostname, localhost.$mydomain, localhost
mydomain = marche.be
myhostname = citoyen2015.marche.be
mynetworks = 127.0.0.0/8 [::ffff:127.0.0.0]/104 [::1]/128
myorigin = /etc/mailname
readme_directory = no
recipient_delimiter = +
relayhost = gatekeeper.marche.be
smtpd_banner = $myhostname ESMTP $mail_name (Debian/GNU)
virtual_alias_maps = proxy:ldap:/etc/postfix/ldap_virtual_aliases.cf
virtual_mailbox_domains = hash:/etc/postfix/virtual_domains
virtual_mailbox_maps = proxy:ldap:/etc/postfix/ldap_virtual_recipients.cf
virtual_transport = dovecot


My ldap_virtual_recipients.cf (same in ldap-citoyen.cf and in 
ldap_virtual_aliases.cf)

server_host = ldap.marche.be
search_base = ou=Users,ou=Citoyens,dc=marche,dc=be
scope = sub
bind = no
version  = 3

#query_filter = 
(&(|(mail=%s)(gosaMailAlternateAddress=%s))(objectClass=gosaMailAccount))
query_filter = (|(gosaMailAlternateAddress=%s)(mail=%s)(uid=%s))
#result_attribute = uid
result_attribute = gosaMailForwardingAddress
