Topic: AD integration

Hello all,

I'm trying to integrate iredmail in AD environment.
I'm using this howto, Ubuntu server 10.04.4 x86, Windows Server 2008 R2. Active directory works as a charm, for the moment..
I've created an account in the AD database that i use to login to Windows clients stations.

First, the command

ldapsearch -x -h ad.mydomain.lan -D 'vmail' -W -b 'cn=users,dc=mydomain,dc=lan'

didn't work for me, i had to use

ldapsearch -x -h ad.mydomain.lan -D 'MYDOMAIN\vmail' -W -b 'cn=users,dc=mydomain,dc=lan'

I've done every changes said in the howto, then i'm stuck when i use the command :

postmap -q accountivecreated@mydomain.lan ldap:/etc/postfix/ad_virtual_mailbox_maps.cf

Ubuntu server returns me this error :

postmap: warning: dict_ldap_lookup: Search error 1: Operations error

There's nothin in windows logs..

Anyone can help me to solve this problem ?

Thanks in advance smile

Re: AD integration

It seems that it's the same error than in the howto begining.
In /etc/postfix/ad_*.cf config files, I've to change

bind_dn         = vmail

by

bind_dn         = MYDOMAIN\vmail

I no longer have the previous error, but nothing appears, so I changed the debug level to 1 in the /etc/postfix/ad_mailbox_maps.cf
So, here's the result :

Re: AD integration

postmap -q accountivecreated@mydomain.lan ldap:/etc/postfix/ad_virtual_mailbox_maps.cf

Please paste content of /etc/postfix/ad_virtual_mailbox_maps.cf here to help troubleshoot. REPLACE sensitive information before posting.

Also, could you please set debug level to 0, then execute postmap with option '-v' again and post output here?

# postmap -v -q accountivecreated@mydomain.lan ldap:/etc/postfix/ad_virtual_mailbox_maps.cf

Re: AD integration

The two first commands are now ok, but i don't know why, but i'll search later..

I've got a problem with the third command now. (the one queries groups)

Here's my ad_virtual_group_maps :

server_host     = ad.mydomain.lan
server_port     = 389
version         = 3
bind            = yes
start_tls       = no
bind_dn         = MYDOMAIN\vmail
bind_pw         = vmailpasswd
search_base     = cn=users,dc=mydomain,dc=lan
scope           = sub
query_filter    = (&(objectClass=group)(mail=%s))
special_result_attribute = member
leaf_result_attribute = mail
result_attribute= userPrincipalName
debuglevel      = 0

And here's the command result with "-v":

PS : I'm sure that "grp_test" exists, and there's users in it.
I tried to make a "distribution" group and put users in it, it's the same result.

Re: AD integration

I've continue the howto despite groups working..

I'm now at the connection test with dovecot.

I can connect to localhost, then i type this command :

. login user@mydomain.lan passwduser

Mail server returned me :

. NO [UNAVAILABLE] Temporary authentication failure.

And, in the Dovecot logs :

Mar 23 15:28:28 auth(default): Error: ldap(user@mydomain.lan,127.0.0.1): ldap_search((&(userPrincipalName=user@mydomain.lan)(objectClass=person)(!(userAccountControl:1.2.840.113556.1.4.803:=2)))) failed: Referral

It means cannot find accounts with LDAP filter "(&(objectClass=group)(mail=grp_test@mydmain.lan))".

As mentioned in the wiki tutorial:

If your group account doesn't contains attribute 'mail' and 'userPrincipalName', please try 'query_filter = (&(objectClass=group)(sAMAccountName=%u))' instead.

I guess you should give it another try.

Please also refer to this forum topic:

Re: AD integration

Hello,

I continue the integration.
When I changed the ad_virtual_group_maps.cf, result was the same.

I used the "-v" argument, and I saw users as members as it had to be, but no line appears without verbose argument.

I continue the howto, and I'm at the Dovecot test step.

I used telnet, it connected wells. When I use ". login myuser@mydomain.lan passworduser" it returns me :

. NO [UNAVAILABLE] Temporary authentication failure.

I looked in Dovecot logs, and there is :

Mar 26 11:47:49 auth(default): Error: ldap(myuser@mydomain.lan,127.0.0.1): ldap_search((&(userPrincipalName=myuser@mydomain.lan)(objectClass=person)(!(userAccountControl:1.2.840.113556.1.4.803:=2)))) failed: Referral

Any advice ?

Thanks smile

Re: AD integration

Could you please post dovecot-ldap.conf here to help troubleshoot?

Re: AD integration

Hello,

To be sure to understand all I do, I delete mail server and I re-install it, it's the 5th time I do that smile

Previously, I had a problem with the Dovecot authentication, it seems it was an error of mine, the howto is OK. Apologies.

But in each re-install I do, I've already the error with the listing of the distribution groups of the AD.

The Distribution group is in the AD "users" folder, and it's name is "grp_test_mail" and there's two users in it.

Here's the ad_virtual_group_maps.cf :

server_host     = adserver.mydomain.lan
server_port     = 389
version         = 3
bind            = yes
start_tls       = no
bind_dn         = vmail@mydomain.lan
bind_pw         = vmail_passwd
search_base     = cn=users,dc=mydomain,dc=lan
scope           = sub
query_filter    = (&(objectClass=group)(mail=%s))
special_result_attribute = member
leaf_result_attribute = mail
result_attribute= userPrincipalName
debuglevel      = 0

When i use the command with the config file above :

postmap -q -v grp_test_mail@mydomain.lan ldap:/etc/postfix/ad_virtual_group_maps.cf

I got his error (the same as in the mail.log file) :

postmap: fatal: open database grp_test_mail@mydomain.lan.db: No such file or directory

huh, grp_test_mail@mydomain.lan.db WTF ?

Thanks in advance smile

Re: AD integration

Did you try:

# postmap -v -q grp_test_mail@mydomain.lan ldap:/xxx

I mean, place '-v' in front of '-q'.

Re: AD integration

In addition, something I can't explain to myself :

In ad_*_maps.cf, bind_dn is a user stored in AD database.

I can't explain how a user (with valid credidentials, OK) can read a whole database and tell if this or this user exists, and if the password of another account isn't wrong. This reasonning is true with ad_sender and ad_virtual_mailbox config files.

However, I'm agree (despite of I don't understand...) when we talk about user accounts...

BUT

When we talk about distribution groups, how a user, which isn't part of any group, can read AD database, and tell "this user or this user" is in "this or this group" ?!

I searched on Google, but my question isn't accurate enought to have a valid answer to me.

Thanks for explain me smile

Re: AD integration

Log says:

postmap: dict_ldap_lookup: /etc/postfix/ad_virtual_group_maps.cf: Searching with filter (&(objectClass=group)(mail=grp_test_mail@mydomain.lan))
postmap: dict_ldap_get_values[1]: Search found 0 match(es)

That means it cannot find accounts with LDAP filter "(&(objectClass=group)(mail=grp_test_mail@mydomain.lan))".
Does your group account has 'mail' attribute? Does it has attribute 'sAMAccountName'?
Please paste the LDIF info of a sample mail group account to help troubleshoot.

Re: AD integration

OK,

I just didn't know that I had to fill "mail adress" in the group properties like on this pic :
http://img11.hostingpics.net/thumbs/mini_305445iredad.jpg

It seems to work now.

Thanks smile

Re: AD integration

I just passed the Roundcube step.

It seems all is OK, but in the Adress Book, I've only groups (like grp_mail_test) but no users.

No errors, nowhere..

Is Adress book must show AD users ?

Thanks smile

EDIT : OK, my fault, same error than before, I must put an email adress in the user's properties.

Re: AD integration

Hello all,

Today is new day, I come with 2 questions :

  • Is there a way that dovecot, don't only search users in CN=users but in the whole domain ?
    For example, I've created an OU (organisationnal unit ), and put a user which "worked" when it was in CN=users. With telnet command, I can't log in with this account...
    In dovecot ldap config files, I deleted CN=users, but it doesn't work...
    But when I use ldapsearch command with this account, it works normally. So, it's a Dovecot "problem", I think.

  • What's the advantage of iRedAdmin with active directory configuration ?

Thanks smile

PS : I forgot the log file :

Apr 18 15:41:49 auth(default): Error: ldap(myuser@mydomain.fr,127.0.0.1): ldap_search((&(userPrincipalName=myuser@mydomain.fr)(objectClass=person)(!(userAccountControl:1.2.840.113556.1.4.803:=2)))) failed: No such object

Sure. Change 'base =' in dovecot-ldap.conf to the one you want. For example:

# OLD SETTING
#base           = cn=users,dc=example,dc=com

# NEW SETTING
base            = dc=example,dc=com

Note: Please make sure your Active Directory server is allowed to search 'dc=example,dc=com'. As i remember, it's not allowed by default. (maybe i was wrong, just a kindly remind.)

iRedAdmin doesn't work with Active Directory, sorry.
It works with OpenLDAP, MySQL, and PostgreSQL (will be available in next release).

I use this tutorial, and it doesn't work.
The Dovecot' log said nothing, no error. But in the telnet shell, it told me

* OK Waiting for authentication process to respond..

but after a little time, I get timeout inactivity and get disconnected. I already have this "error" before make change in Windows Server.

I admit, I don't understand what you're talking about when you said allowed to search 'dc=example,dc=com'. The problem is, I don't know what to search on Google, I understand it deals with Windows restriction but nothing more...
Why does it work with ldapsearch command but not with dovecot ?

if it works with ldapsearch, then it should work in Dovecot too.
Did you try to set 'mail_debug = yes' in Dovecot, restart Dovecot, then monitor Dovecot log file?
Could you please paste the whole dovecot-ldap.conf? REPLACE password by 'xxx' to hide sensitive information before posting.

Re: AD integration

Here's the dovecot log file when i try telnet connexion (no error seems to worry dovecot...) :

And the dovecot-ldap.conf :

hosts           = dc.mydomain.lan:389
ldap_version    = 3
auth_bind       = yes
dn              = MYDOMAIN\vmail
dnpass          = passwd_vmail
base            = dc=mydomain,dc=lan
scope           = subtree
deref           = never
user_filter     = (&(userPrincipalName=%u)(objectClass=person)(!(userAccountControl:1.2.840.113556.1.4.803:=2)))
pass_filter     = (&(userPrincipalName=%u)(objectClass=person)(!(userAccountControl:1.2.840.113556.1.4.803:=2)))
pass_attrs      = userPassword=password
default_pass_scheme = CRYPT
user_attrs      = =home=/home/mail/%Ld/%Ln/Maildir/,=mail=maildir:/home/mail/%Ld/%Ln/Maildir/

The problem is, now, users I don't move to an OU, which is always in "Users" don't work since I changed "base" in dovecot-ldap.conf. I think "Users" group is considerate like an OU to the mail side.

Re: AD integration

Does below command work for you?

# ldapsearch -x -b 'dc=mydomain,dc=lan' -D 'MYDOMAIN\vmail' -W "(&(userPrincipalName=user@mypublicdomain.fr)(objectClass=person)(!(userAccountControl:1.2.840.113556.1.4.803:=2)))"

if not, please add '-d 256' after 'ldapsearch' and try again. Paste output of both commands here please (REMOVE sensitive info before posting)

Re: AD integration

I tried, it doesn't work. Same result with -d 256.
I tried with MYDOMAIN\vmail and vmail@mydomain.lan

Here's the error :

        additional info: invalid DN

It complains "MYDOMAIN\vmail" is a invalid DN. Did you try to use 'vmail' instead? For example:
