Hello, I need to setup postfix mail server to query ACTIVE DIRECTORY. I am looking for a detailed tutorial explaining every steps I have to follow. Thanks in advance. Soja
https://www.howtoforge.com/postfix-dovecot-authentication-against-active-directory-on-centos-5.x It's for centos 5, but since you did not mention your OS I think that should do ;-) The setup you want to do is relatively complicated. You might start as Step 1 by reading a lot of documentation... http://www.postfix.org/LDAP_README.html You can use the postfix config from here: https://docs.iredmail.org/active.directory.html
Thanks for your interst and sorry for the lack of information. It was my mistake. In fact, to make it short my configuration is : Debian 10 (Buster) + Postfix + Dovecot + MS Windows Server 2016 (LDAP server) I just want to note that I have already tried these steps without result. Is there a synthetic way to sort out my problem ? Thanks in advance
We still do not know, 'what' exactly your problem is. Is not a good description of your problem! What you want to achieve is not a trivial task which could be solved by installing something or pasting one line of code and you are good to go. It is complicated and requires some knowledge. If you do not have it at this time you need to read the manual. Sorry for that.
You are right. I am sorry. It'd better to start to an exct clarified issue. To summarize : AD - postfix/dovecot is already installed. Now, I am testing if users are queried from AD with the following command : Here after the content of ldap_virtual_recipients.cf : bind = yes bind_dn = cn=vmail, cn=users, dc=mydomain, dc=com bin_pw=******* server_host=192.168.1.2 search_base= ou=people,dc=mydomain,dc=local version = 3 scope=sub query_filter= (&(mail=%s) (mailEnabled=TRUE)) result_attribute = mail Here after what I get when I test with the following command postmap -v -q [email protected] ldap:/etc/postfix/ldap_virtual_recipients.cf postmap: name_mask: all postmap: inet_addr_local: configured 2 IPv4 addresses postmap: inet_addr_local: configured 2 IPv6 addresses postmap: dict_ldap_open: Using LDAP source /etc/postfix/ldap_virtual_recipients.cf postmap: cfg_get_str: /etc/postfix/ldap_virtual_recipients.cf: server_host = 192.168.1.2 postmap: cfg_get_int: /etc/postfix/ldap_virtual_recipients.cf: server_port = 389 postmap: cfg_get_int: /etc/postfix/ldap_virtual_recipients.cf: version = 3 postmap: dict_ldap_open: /etc/postfix/ldap_virtual_recipients.cf server_host URL is ldap://192.168.1.2:389 postmap: cfg_get_str: /etc/postfix/ldap_virtual_recipients.cf: scope = sub postmap: cfg_get_str: /etc/postfix/ldap_virtual_recipients.cf: search_base = ou=people,dc=mydomain,dc=com postmap: cfg_get_int: /etc/postfix/ldap_virtual_recipients.cf: timeout = 10 postmap: cfg_get_str: /etc/postfix/ldap_virtual_recipients.cf: query_filter = (&(mail=%s)(mailEnabled=TRUE)) postmap: cfg_get_str: /etc/postfix/ldap_virtual_recipients.cf: result_format = <NULL> postmap: cfg_get_str: /etc/postfix/ldap_virtual_recipients.cf: result_filter = %s postmap: cfg_get_str: /etc/postfix/ldap_virtual_recipients.cf: domain = mydomain.com postmap: cfg_get_str: /etc/postfix/ldap_virtual_recipients.cf: terminal_result_attribute = postmap: cfg_get_str: /etc/postfix/ldap_virtual_recipients.cf: leaf_result_attribute = postmap: cfg_get_str: /etc/postfix/ldap_virtual_recipients.cf: result_attribute = mail postmap: cfg_get_str: /etc/postfix/ldap_virtual_recipients.cf: special_result_attribute = postmap: cfg_get_str: /etc/postfix/ldap_virtual_recipients.cf: bind = yes postmap: cfg_get_str: /etc/postfix/ldap_virtual_recipients.cf: bind_dn = cn=Administrateur,cn=users,dc=mydomain,dc=com postmap: cfg_get_str: /etc/postfix/ldap_virtual_recipients.cf: bind_pw = StdUpBibb.4652 postmap: cfg_get_bool: /etc/postfix/ldap_virtual_recipients.cf: cache = off postmap: cfg_get_int: /etc/postfix/ldap_virtual_recipients.cf: cache_expiry = -1 postmap: cfg_get_int: /etc/postfix/ldap_virtual_recipients.cf: cache_size = -1 postmap: cfg_get_int: /etc/postfix/ldap_virtual_recipients.cf: recursion_limit = 1000 postmap: cfg_get_int: /etc/postfix/ldap_virtual_recipients.cf: expansion_limit = 0 postmap: cfg_get_int: /etc/postfix/ldap_virtual_recipients.cf: size_limit = 0 postmap: cfg_get_int: /etc/postfix/ldap_virtual_recipients.cf: dereference = 0 postmap: cfg_get_bool: /etc/postfix/ldap_virtual_recipients.cf: chase_referrals = off postmap: cfg_get_bool: /etc/postfix/ldap_virtual_recipients.cf: start_tls = off postmap: cfg_get_bool: /etc/postfix/ldap_virtual_recipients.cf: tls_require_cert = off postmap: cfg_get_str: /etc/postfix/ldap_virtual_recipients.cf: tls_ca_cert_file = postmap: cfg_get_str: /etc/postfix/ldap_virtual_recipients.cf: tls_ca_cert_dir = postmap: cfg_get_str: /etc/postfix/ldap_virtual_recipients.cf: tls_cert = postmap: cfg_get_str: /etc/postfix/ldap_virtual_recipients.cf: tls_key = postmap: cfg_get_str: /etc/postfix/ldap_virtual_recipients.cf: tls_random_file = postmap: cfg_get_str: /etc/postfix/ldap_virtual_recipients.cf: tls_cipher_suite = postmap: cfg_get_int: /etc/postfix/ldap_virtual_recipients.cf: debuglevel = 0 postmap: dict_open: ldap:/etc/postfix/ldap_virtual_recipients.cf postmap: dict_ldap_lookup: In dict_ldap_lookup postmap: match_string: /etc/postfix/ldap_virtual_recipients.cf: mydomain.com ~? mydomain.com postmap: dict_ldap_lookup: No existing connection for LDAP source /etc/postfix/ldap_virtual_recipients.cf, reopening postmap: dict_ldap_connect: Connecting to server ldap://192.168.1.2:389 postmap: dict_ldap_connect: Actual Protocol version used is 3. postmap: dict_ldap_connect: Binding to server ldap://192.168.1.2:389 with dn cn=Administrateur,cn=users,dc=mydomain,dc=com postmap: dict_ldap_connect: Successful bind to server ldap://192.168.1.2:389 with dn cn=Administrateur,cn=users,dc=mydomain,dc=com postmap: dict_ldap_connect: Cached connection handle for LDAP source /etc/postfix/ldap_virtual_recipients.cf postmap: dict_ldap_lookup: /etc/postfix/ldap_virtual_recipients.cf: Searching with filter (&([email protected])(mailEnabled=TRUE)) postmap: warning: dict_ldap_lookup: /etc/postfix/ldap_virtual_recipients.cf: Search base 'ou=people,dc=mydomain,dc=com' not found: 32: No such object postmap: fatal: table ldap:/etc/postfix/ldap_virtual_recipients.cf: query error: Success In my opinion, there are some incoherence in last 2 lines. Many thanks for the help to detect what is wrongly configured.
Finally, I was able to sort out my problem of querying AD with postmap by changing the following lines in my configuration file query_filter = (&(&(objectCategory=person) (sAMAccountName=%u)) (!(userAccountControl:1.2.840.113556.1.4.803:=2))) result_attribute = mail Maybe it can help. Anyway, thanks for the interaction.
