Topic: iRedMail with freeIPA LDAP server integration

==== REQUIRED BASIC INFO OF YOUR IREDMAIL SERVER ====
- iRedMail version (check /etc/iredmail-release): 1.6.4 OPENLDAP edition.
- Deployed with iRedMail Easy or the downloadable installer? downloadable
- Linux/BSD distribution name and version: ubuntu 22.04
- Store mail accounts in which backend (LDAP/MySQL/PGSQL): RedHat Identity management (aka freeIPA)
- Web server (Apache or Nginx): nginx
- Manage mail accounts with iRedAdmin-Pro? NO
- [IMPORTANT] Related original log or error message is required if you're experiencing an issue.
====

Hi. I have already had an LDAP server (Redhat Identity Management server also known as freeIPA server). instead of openLDAP, I want to use this as my LDAP server.

my e-mail domain is: abra.co.uk
my LDAP domain: abra.local

I know, they are different..

I have followed your AD integration doc. I have successfully created ldap user to query LDAP users in my RedHat IDm server.
but I think I have a problem with filters and result_attributes. postmap returns nothing and I am sharing the verbose output below. any help is much appreciated..

Note: I have not created any mail group. I also need help on this

I have changed ad_sender_login_maps.cf with the following:
/etc/postfix/ad_sender_login_maps.cf

server_host     = freeipa.abra.local
server_port     = 389
version         = 3

Re: iRedMail with freeIPA LDAP server integration

Hi
I solved my problem. here are the steps . I hope it will give benefit to other people

freeIPA LDAP entegrasyonu:

There is an official doc for AD integration. I have used this doc.
docs.iredmail.org/active.directory.html
this also opened some ideas on solution:
forum.iredmail.org/topic15548-external-domain-with-ldap-ad-authentication.htm

First step is to create a user to talk with the LDAP (freeIPA) server
maler/yourSecretPassword (on freeIPA)

With the following query, we understood that, we can query users from our LDAP server
  ldapsearch -x -H ldap://ipa.abra.local -D 'uid=maler,cn=users,cn=accounts,dc=abra,dc=local' -W -b 'cn=users,cn=accounts,dc=abra,dc=local'

2. Step
POSTFIX integration
Note: we have a special case here
mail domain is: abra.com
LDAP domain is: abra.local
so we needed to constrcurt result format for the offical one (abra.com) not for the LDAP one
Create necessary files for external LDAP (freeIPA) configuration

root@mail:~# cat /etc/postfix/ad_sender_login_maps.cf
server_host     = ipa.abra.local
server_port     = 389
version         = 3
bind            = yes
start_tls       = no
bind_dn         = uid=maler,cn=users,cn=accounts,dc=abra,dc=local
bind_pw         = yourSecretPassword
search_base     = cn=users,cn=accounts,dc=abra,dc=local
scope           = sub
query_filter    = (&(objectClass=person)(uid=%u))
result_attribute= mail
result_format    = %u@abra.com
debuglevel      = 0
root@mail:~# cat /etc/postfix/ad_virtual_mailbox_maps.cf
server_host     = ipa.abra.local
server_port     = 389
version         = 3
bind            = yes
start_tls       = no
bind_dn         = uid=maler,cn=users,cn=accounts,dc=abra,dc=local
bind_pw         = yourSecretPassword
search_base     = cn=users,cn=accounts,dc=abra,dc=local
scope           = sub
query_filter    =  (&(objectClass=person)(uid=%u))
result_attribute= mail
result_format   = abra.com/%u/Maildir/
debuglevel      = 0
root@mail:~# cat /etc/postfix/ad_virtual_group_maps.cf
server_host     = ipa.abra.local
server_port     = 389
version         = 3
bind            = yes
start_tls       = no
bind_dn         = uid=maler,cn=users,cn=accounts,dc=abra,dc=local
bind_pw         = yourSecretPassword
search_base     = cn=groups,cn=accounts,dc=abra,dc=local
scope           = sub
query_filter    = (&(objectClass=posixgroup)(cn=%u))
special_result_attribute = member
#leaf_result_attribute = mail
result_attribute= uid
debuglevel      = 0


We checked that this configuration is working:

postmap -q maler@abra.com ldap:/etc/postfix/ad_virtual_mailbox_maps.cf
postmap -q maler@abra.com ldap:/etc/postfix/ad_sender_login_maps.cf
# i created this group (mailers) and made all users members of this group on freeIPA
postmap -q mailers@abra.com ldap:/etc/postfix/ad_virtual_group_maps.cf

3. Step
DOVECOT integration
root@mail:~# cat /etc/dovecot/dovecot-ldap.conf
hosts           = ipa.abra.local:389
ldap_version    = 3
auth_bind       = yes
dn              = uid=maler,cn=users,cn=accounts,dc=abra,dc=local
dnpass          = yourSecretPassword
base            = cn=users,cn=accounts,dc=abra,dc=local
scope           = subtree
deref           = never
debug_level     = 0

# Below two are required by command 'doveadm mailbox ...'
iterate_attrs   = uid=user
iterate_filter  = (&(objectClass=person)(uid=*))

user_filter     = (&(objectClass=person)(uid=%n))
user_attrs      = mail=master_user,mail=user,=home=/var/maler/maler1/%Ld/%Ln/,=mail=maildir:~/Maildir/

# Used for dn lookup
pass_filter     = (&(objectClass=person)(uid=%n))
pass_attrs      = userPassword=password
default_pass_scheme = CRYPT

We tested this config with
telnet localhost 143

. login maler@abra.com yourSecretPassword


4th step
ROUNDCUBE (mail web interface) integration

root@mail:~# cat /opt/www/roundcubemail/config/config.inc.php
…
// Global LDAP address book.
$config['ldap_public']["global_ldap_abook"] = array(

$config['autocomplete_addressbooks'] = array('sql', 'global_ldap_abook');

Re: iRedMail with freeIPA LDAP server integration

Hello mskaraca,

your feedback was very helpful for me and my setup, but i have a problem when the FreeIPA user has ipaUserAuthType set to otp in FreeIPA world mean password+otp in the password filed.

unfortunately i think that dovecot make multiple request to ldap backend and this is very bad when you have totp with 60s.

is there any workaround to this issue ?

@ZhangHuangbin

many Regards
