Hi all
I set up a mail server AD + Postfix + Dovecot + Kerberos
This works fine for only one domain
In the attribute mail=test@test.com, in otherMailbox=vasya@otherdoamin.com,petya@another.net

Config files:
Postfix
ldap-users.cf
server_host = server
search_base = dc=cn,dc=energy
version = 3
bind = yes
bind_dn = ldapmail@cn.energy
bind_pw = passwd

query_filter = (&(objectCategory=person)(|(mail=%s)(otherMailbox=%s))(!(userAccountControl=514)))
result_attribute = mail otherMailbox
result_format = %d/%u

dovecot-ldap.conf
hosts = server:3268
debug_level = 2
dn = ldapmail
dnpass = passwd
tls = no
auth_bind = yes
auth_bind_userdn = cn.energy\%u
ldap_version = 3
base = dc=cn, dc=energy
deref = searching
scope = subtree
user_attrs = mail=user,uid=vmail, gid=vmail
user_filter = (&(objectclass=person)(|(sAMAccountName=%n)(otherMailbox=%n))(!(userAccountControl=514)))
default_pass_scheme = CRYPT

postconf:
attribute mail
postmap -q ross@test.com ldap:/etc/postfix/ldap-users.cf
another.net/petya,otherdoamin.com/vasya,test@test.com/ross

attribute otherMailbox
postmap -q ross@otherdoamin.com ldap:/etc/postfix/ldap-users.cf
another.net/petya,otherdoamin.com/vasya,test@test.com/ross

The filter searches and finds the correct.
Just does not work result_format ???

example:
another.net/petya,otherdoamin.com/vasya,test@test.com/ross
this name one directory ! hmmm dovecot dont find it

Many thanks for your help.
