postfix/dovecotを使ったメールサーバを作成する際、そのサーバ上でユーザ向けメールサービスを提供する場合にLDA設定を行う必要がある。
調べると dovecot-lda を使って保存するのがよさそうではある
参考資料
dovecot側 「Dovecot LDA」「Dovecot LDA Examples」「Dovecot LDA with Postfix」
ただ、これをActive Directory/LDAPと連携させる場合の記述についてがいまいちはっきりしない。
ベースとするのは「Dovecot LDA with Postfix」の「Virtual users」にある記述で、/etc/postfix/master.cf に dovecotの記述を追加して、 /etc/postfix/main.cf に dovecot_destination_recipient_limit , virtual_mailbox_domains , virtual_transport の設定を追加する、と読める。
ただ、これだけだとメールを格納する場所について書いてないなぁ、と思いつつ試してみた
その結果、 virtual_transport=dovecot を設定した場合は、 postfix側で “virtual_mailbox_maps= ldap:/etc/postfix/ldap-mailbox.cf”とか”virtual_mailbox_base= /var/vmail”とかの設定を入れて /etc/postfix/ldap-mailbox.cf でLDAPに関する設定を書いたりする必要なく、dovecot側で行ったLDAP連携設定をもとにdovecot側で処理してくれる、ということが分かった
で・・・これの確認をするための副産物として、 virtual_transport=dovecotとしているのに virtual_mailbox_maps= ldap:/etc/postfix/ldap-mailbox.cf とかpostfix側でLDAPを直接見に行くような設定をしてしまうとどうなるの？というのを確認していた（意図せずに・・・
gihyoにあるそろそろLDAPにしてみないか？第１５回「FDS＋Postfixでメールサーバ管理」と「デージーネットのOSS postLDAPadmin Appendix」を参照しつついろいろ検討
まず、今回、/etc/postfix/master.cf の最下行にdovecotに関する２行を追加した
[root@mail postfix]# tail /etc/postfix/master.cf
#
#scalemail-backend unix - n n - 2 pipe
# flags=R user=scalemail argv=/usr/lib/scalemail/bin/scalemail-store
# ${nexthop} ${user} ${extension}
#
#mailman unix - n n - - pipe
# flags=FRX user=list argv=/usr/lib/mailman/bin/postfix-to-mailman.py
# ${nexthop} ${user}
dovecot unix - n n - - pipe
flags=DRhu user=vmail:vmail argv=/usr/libexec/dovecot/dovecot-lda -f ${sender} -d ${recipient}
[root@mail postfix]#
そして、/etc/postfix/main.cf には以下を追加した
[root@mail postfix]# tail -10 /etc/postfix/main.cf
#
#
virtual_mailbox_domains = adsample.local
virtual_mailbox_maps= ldap:/etc/postfix/ldap-mailbox.cf
virtual_mailbox_base= /var/vmail
virtual_uid_maps= static:1000
virtual_gid_maps= static:1000
virtual_transport= dovecot
dovecot_destination_recipient_limit = 1
[root@mail postfix]#
で、postfix側のLDAP連携設定は以下とした
[root@mail postfix]# cat /etc/postfix/ldap-mailbox.cf
#server_host=192.168.122.10
server_host=ldaps://192.168.122.10
#server_port=636
#search_base=dc=adsample,dc=local
search_base=cn=Users,dc=adsample,dc=local
scope=sub
#query_filter = (&(objectClass=user)(mail=%s))
query_filter = (&(objectClass=user)(userPrincipalName=%s))
result_attribute = samAccountName
result_filter = /var/mail/%s/Maildir/
bind=yes
bind_dn=vmail@adsample.local
bind_pw=パスワード
version=3
#start_tls=yes
#debuglevel=10
[root@mail postfix]#
とりあえず「debuglevel=10」というのは調査中に有効にしていた値
virtual_mailbox_maps で取得できる情報として期待されているものは メールを保存するディレクトリ名 の模様
コメントとなっている「query_filter = (&(objectClass=user)(mail=%s))」はActive Directoryベースだとmailってないので使わない。ユーザ名のみの場合は「samAccountName=%s」、ドメイン名付きの場合は「userPrincipalName=%s」かな、というところで設定
取得できてるかどうかは「postmap -q ユーザ名 ldap:/～」で確認
[root@mail ~]# postmap -q testuser1@adsample.local ldap:/etc/postfix/ldap-mailbox.cf
/var/mail/testuser1/Maildir/
[root@mail ~]#
想定しているディレクトリ名が出力されればOK
-vオプションをつけると検索内容の詳細が確認できる。

それっぽい動作をすることを確認して、postfixを再起動してみたところ”virtual_transport= dovecot”設定を無視して postfix側でLDAPを見に行くことを確認。(/etc/postfix/ldap-mailbox.cfにdebuglevel=10を設定すると、 /var/log/maillog に詳細ログが出ているので)
どうやら、2025年5月時点では postfix/dovecotでActive Directory連携するときは、postfix側ではLDAP連携をする必要はないようだ（aliasなどをAD側で設定している場合は別)
最終的に行った設定内容
結局のところ「Dovecot LDA with Postfix」の Virutal users記載ベースで/etc/postfix/master.cfの末尾にdovecot用設定2行追加。(元ネタでは /usr/local/libexec以下にあるけどRHEL9では/usr/libexecという違いに注意)

なお、この時にdovecot側のLDAP連携設定は以下となっている。(メールソフト側でIMAP/POP3用に入力するユーザ名をドメイン名付きにしたい場合はuserPrincipalName、ユーザ名のみにしたい場合は samAccountName を使う)

[root@mail ~]#
また /etc/dovecot/conf.d/10-mail.conf に mail_location = maildir:/var/mail/%n/Maildir という設定を追加している。

エラー対処
/var/log/maillog を見てたら下記のようなpermission問題があった

エラー対処を調べると2019年1月のiredmailフォーラムの「Re: Error: net_connect_unix(/var/run/dovecot/stats-writer) failed」 が出てくる
これだと /etc/dovecot/dovecot.conf に直接追加しているが、 /etc/dovecot/conf.d/に新しいファイルを作って追加することにした
[root@mail conf.d]# vi /etc/dovecot/conf.d/12-stat.conf
[root@mail conf.d]# cat /etc/dovecot/conf.d/12-stat.conf
service stats {
unix_listener stats-reader {

}
unix_listener stats-writer {
user = vmail
group = vmail

}
}
[root@mail conf.d]# systemctl restart dovecot
[root@mail conf.d]#
これで出力されなくなった
メール送信時の細かい設定について
/etc/dovecot/dovecot-ldap.conf.ext と /etc/dovecot/conf.d/auth-ldap.conf.ext のそれぞれでuid/gidに関する設定を入れているが、それぞれの必要性について再検証
というのは、設定してるなかで、片方だけ設定を入れているとmissingログが出てたから両方入れた・・・はずだったんだけど、それって正しいの？という検証
まずは/etc/dovecot/conf.d/99-debug.conf にdebugログ出力設定を書いて 実施
[root@mail ~]# cat /etc/dovecot/conf.d/99-debug.conf
auth_debug=yes
auth_debug_passwords=yes
auth_verbose=yes
auth_verbose_passwords=yes
verbose_proctitle=yes

missing 出力がない？？
そもそも、同じログレベル出力なのに、出力された内容に差がありすぎるんですが・・・
dovecot-ldap.conf.ext に “user_attrs = =uid=1000, =gid=1000″,”pass_attrs = =uid=1000, =gid=1000” を設定するだけでいける？
